AUTOPILOT TEST BENCH
Project Area of Specialization Augmented and Virtual RealityProject SummaryA simulation system of the aviation autopilot for teaching and training is established. Autopilot consisting of three relatively independent channels (the inclined channel, course channel and pitch channel) is designed to meet the simulated flight of the aviation autopilot in the steady status and manipulation status.A simulation system of the aviation autopilot for teaching and training is established. By analyzing the function, structure and principle of the aviation autopilot, the aviation autopilot simulation system is established to realize the real-time control of flight environment. The simulation system mainly refers to the real-time control of the steady status and manipulation status in the inclined channel, course channel and pitch channel. The system has the following characteristics:
convenient operation, stable work, convenient observation.The UAV Test Bench was built using LabVIEW combined with Pixhawk. The Test Bench was used to develop and test the autopilot software used within the UAV Controller. The autopilot was developed for an RC model aircraft within the flight simulator and then deployed to the real UAV without change.
The main objective is to facilitate the organisations making autopilot.As its cost is very effective and as in aircraft autopilot is one of the most important feature or component.So its efficiency is very important and a single error or delay can lead to tragic accident. So by using our Autopilot test bench one can test autopilot module in Ground and if required we can make necessary changes.
Project Implementation MethodAutopilot consists of three relatively independent channels, namely: the inclined channel, course channel and pitch channel. The inclined channel controls aileron; the course channel controls elevator; the pitch channel controls rudder. Working principle of each channel.The manipulation components are not directly effect on the channel. Sensitive element: measure the aircraft state and motion parameters (angle, angular velocity, height, etc.) and convert them into the electrical signals which are proportional to the parameters. Manipulation components: electrical signals controlling the aircraft are generated by the artificial manipulation. Server: The rudder surface is deflect to a angle by the server (a power plant). The rudder angle is proportional to electrical signals controlled by the sensitive components and manipulation components.The implementation of the hardware in the loop done by sequential steps. First one adding the desired autopilot in the nonlinear flight simulation model, where the autopilot consists of pre-filter used to smooth the output of the lag circuit and then summation occurs with the feedback gyro voltage to produce the error voltage signal.It is possible to obtain the overall autopilot transfer function of the system through a suitable combination utilizing some basic rules of block diagram transformation to reduce the original diagram. In order to represent the desired controller in one block diagram to test under software-in-loop pre-filter block diagram shifted after summation point and the gyro simulated feedback voltage is modified to modified voltage via multiplication by the inverse of the pre-filter circuit.
Benefits of the ProjectThe test bench has the advantage of providing a secure environment in which to test the autopilot. It will help you save money. We may use the test bench to determine if our autopilot is functioning properly. Auto-pilot is a tool that generates accurate and meaningful benchmark results.
Technical Details of Final DeliverableThis has two implications, first in making sure that the project performs the task or function asked of it and secondly that accurate and complete documentation is produced for the end user. If the project deliverable is a physical product then the testing regime will usually be quite straightforward and involve a predetermined set of measurements that are compared to the original specification.
1) Creating a specialist test team.
2) Designing the software for 'testability'.
3) Making testing an integral part of software development.
4) Ensuring requirement traceability to and from tests.
5) Automating as much of the testing process as possible.
6) Integrating testing with the change management processes.
