Could be people who are going to talk about one of the most important topics in Rome, which is the
guidance, navigation and control of the guidance, navigation and control, or one of the huge topics
in this area which themselves are screaming at or even understand the topic in general so as to make
you acquainted with the important concepts in the topic.
Let us begin now with the understanding of the.
Drones are used in an increasing number of civilian applications, but inspecting and exploring the
duties in complex environments, just as Australia has accepted autonomous guidance, navigation and
control, GNC are required to achieve these missions without Ditech of using the control, guidance
and navigation systems that was developed for rockets.
The systems gained more widespread use with their guided missiles and.
The figure on the sexual assault, a simple log diagram of a GMC system in a room consists of three
essential parts of Ireland system that students are drawn towards a desired state, education target,
etc., a navigation system that tracks the current location of the dorm and estimates that state and
a controlled autopilot that accepts guidance commands and uses navigation data to generate the actual
accurate signals to follow the guidance objectives, as well as to stabilize the vehicle attitude.
Let's look at this route guidance, navigation and control of these in more detail.
A guidance system can be defined as a driver of whatever he can to achieve some vision example, reach
a destination while guaranteeing safety example, avoiding obstacles and put on the navigation system
and use this targeting information to send signals to the flight control system that will allow the
vehicle reach its destination within the constraints of the vehicle, a guidance system that has the
rule of planning the flight path and generating the desired state.
The disposition will also be heading in hope.
It must be tracked by the people that are operating.
Drones are operated remotely by a human operator from the gun control station or use rudimentary guidance
systems just following preplanned or manually provided points or different trajectories.
This is sufficient for operating at high altitudes for reconnaissance and exploration.
However, drones will require more advanced guidance capabilities to achieve more complex tasks and
missions for the more small and micro.
Drones are generally designed to protect the altitude and flexibility and dynamic environments.
Therefore, our advanced guidance and navigation capabilities are necessary to take opticals, mapped
environment and flight than the flight path.
Landing gear and flight path to victory is the chief problem, and almost beyond the basic difficulties,
partially known and changing environments, extraneous factors such as stress and computation, complexity,
because tragically, any problem is easily solved using mathematical optimization methods computationally
demanding to address these issues, guidance problems can be simplified according to the intended application
and the required of the approaches for group planning.
One one can take to be different by evolutionary algorithms, except that currently there is growing
interest in increasingly developing guidance systems that are able to tackle several operational events
without operator intervention, for example, depending on the detection of up to or changes in the
mission or in whatever configuration, guidance capabilities can also increased integration with other
drones, unmanned vehicles who have published ordinator missions in order to develop appropriate guidance
technologies.
One needs to understand and evaluate the required autonomy level.
The letter can be characterized based on the complexity of operational objective vehicle capabilities,
environmental elements and applying knowledge about these elements.
Generally, as autonomy increases, the drones can operate in more complex environments and execute
more complex tasks.
But this operating knowledge and less operator interaction with the reader can do for various influences,
which drives economic capabilities that are critical for future operations.
In the broad sense, navigation is the art of determining whether you are fully autonomous vehicles
and robots, and navigation can be defined as a process of extracting information about the vehicle's
self motion and also the surrounding environment.
This information can be metric that as distances or topological landmarks and other cues that are useful
to achieve the task and to guarantee safety.
For example, using optical flow to avoid obstacles, the navigation system plays a key role in their
craft.
Typically, standard navigation algorithms combine information from many sources and sensors reading
maps to make the vehicle's attitude and eye velocity and position with respect to some fixed point of
reference or relative to some target.
Advanced navigation systems include also mapping, obstacle detection, localization, etc, navigation
outputs are used in guidance and control and affect the performance of flight and which industry.
Much work with you have been convicted using the initial measurement system and global positioning system
to use to achieve autonomous flight and execute the mission, the most used navigation systems are heading
a different system and inertial navigation system.
Each of us is data from three to three meters and three magnetometers to estimate the vehicle's IQ and
included, the Ironist also uses the same sensors to simulate the velocity and position relative to
the starting point.
Online is the first indication is it is growing at us in velocity and position estimates.
Therefore, inertial navigation is usually used to supplement other navigation systems, providing a
higher degree of accuracy than is possible.
But the use of any single system.
Indeed, we rely on ironist and global navigation systems that just provide position and velocity.
Information for navigation for GM is lacking in the in spaces, which is commonly used to provide the
navigation solution.
Furthermore, most robotic missions are defined by the environment that they're in.
Navigation is necessary to achieve these missions.
Mapping and obstacle detection can be performed using active sensors, radar, laser range finder or
passive imaging since the camera phones, ships, etc..
Through this complex, navigation systems typically have multiple redundancies where drift improves
accuracy and I stress isn't a great system failure.
Navigation systems therefore take multiple inputs from many different sensors built into the system
and extend the government through the world.
The most common approach to combining the navigation data to resolve the current position.
However, there are multiple approaches used census data such as particle filters, etc..
The AP is an integrated system of hardware and software of guidance, navigation and control.
Who visited Bowen is capable of getting a range of lights on the program flight to the basic point flight
with advanced autonomous flight and the flight, avoiding the obstacles and carrying out the project
plan in realtime by itself.
In The Man Idiot as a result of the commission and decision making, in other words, guidance and by
the way, is pilot free and that needs to be cleared by the onboard computer and the ground support
system.
On the other hand, the flight controller is an integrated system of hardware and software that carries
out the flight by keeping the Steve Inskeep in accordance with a given project.
In the case of a flight of commercially available hobbyists or whatever, the autopilot is implemented
with only the new world order structure.
In this case, the flight controllers continues to command.
But controlling the traditional speed of model is the input of a pilot while keeping the plane's altitude,
aka Steve with Steve.
And refers to the manipulation of the forces by the of controls, trustor, etc, needed to execute
guidance commands while maintaining the stability.
Gravies and Brauns required hardware and software elements that will allow the aircraft to be controlled
remotely, either directly by the pilot or autonomously by onboard computer, maybe flight dynamics
are highly variable and non-linear, and maintaining attractive and stability may require continuous
computation and readjustment of aircraft flight systems.
The control system includes the control laws to compute inputs for the intruders to produce and forces
that act on its Three-Dimensional position on the controller.
It's not an easy task and it is a multi input, multiple or even under actuator, unstable and highly
complex system.
Many traditional control strategies have been used over the years, but the control of behaviors such
as equality, computers, working in manual, more model and pretending to transmit commands from the
joystick and other controls to the game in order to activate the required aircraft systems for fixed
wing uses, the pilot may be manually controlling the total.
For helicopter control can act on the concisely collective pitch rather than the.
Summarized in that introduction to what guidance control and the region's voted for students to go to
these contests very carefully to understand is one of the most frequent topics in the industry.
And many jobs are currently present in the industry.
Are people what experts in this area it is, encourage their students to explore more details to get
into computer navigation.
We'll also be talking about some of the parts of it in the upcoming lectures.
Thank you.
