Digital Autopilot Design

This thesis attempts to research and design the digital autopilot, which based on the××project of the National Key Laboratory of Transient Physics. The following jobs are finished in this research:Designing the systems solutions. It researches the system structures and theory of working of the three-channel: the pitching loop, the yawing loop and the roll loop. Describes the requirement and target of the platform designing, as well as the realizing method.Designing the hardware of autopilot. Including: the controller board (F2812 function board, sample adjust board, prepositive magnify electrocircuit of PWM signals) and the derive board. The thesis gives a particular description on the controller board, on which the MCU is TMS320F2812 and the ADC uses the F2812 ADC module.Designing the software of autopilot. The primary task is to complete the software designs of controller. Including four segments: ADC sampling, ADC error compensate, realizing the arithmetic of PID and producing the PWM signals. The control method, with respect to the software, is integral-separated PID.Designing the simulation models of the three-channel stable stance loops, and analysing them. The thesis separately establishes simulation models of the three channel stable loops using MATLAB/Simulink. Then carry on the parameter choice and design the emendation link. At last, it carries on the simulation analysis to the three channel stable loops.Debugging the system. Confirms the content of debugging the system, provides the resolvent of issues.
