The Design and Simulation of Digital Controller for Aircraft Control System

The design and optimization of aircraft controller parameters is an important task in the design of control system. Considering the disadvantages of low efficiency and high requirement for design experience in optimization, this paper realizes an intelligent design and simulation of control parameters based on genetic algorithm-GA. Based on an aircraft rigid body movement model, a PD controller is designed to makes the control system stable within the specified margin, and a digital filter is designed to suppress elastic vibration. At last, a simulation shows that our method can reduce the dependence on engineering design experience and optimization, it can make the designed control parameters meet the established performance indicators, and make some explorations and attempts for intelligent design of control system parameters.
