Abstract

Abstract

In order to improve the disturbance isolation degree of aerial photoelectrical stabilized platform, a new controller is designed to replace the traditional PI controller. The new controller utilizes the pseudo-derivative feedback (PDF) control technology and high-gain acceleration feedback based on current feedback, speed feedback and position feedback on the traditional platform. When flight simulator is influenced by 1 degree, 0-2.5 Hz sinusoidal interference, compared with the traditional aerial photoelectrical stabilized platform, the step response overshoot of the platform based on PDF and acceleration feedback system decreases by about 7.8%, and the disturbance isolation degree increases by about 8.7 dB. Besides, compared with the aerial photoelectrical stabilized platform based on PI controller and acceleration feedback control system, the step response overshoot of the platform based on PDF and acceleration feedback system can reduce by about 2.6%, and the transition process of the platform is faster. The control system can effectively restrain the influence from disturbance torque, and this makes the system more common and useful.
