Abstract: The airborne opto-electric stable platform model was analyzed and simplified to K/s with current loop. The disturbance to the platform stability and the disturbance rejection method were illustrated. The traditional square lag-lead compensation method, its strengths and weaknesses were introduced. The repetitive controller and Active Disturbance Rejection Controller (ADRC) were described. A repetitive controller and a two stage ADRC were designed, which were integrated into a new controller system taking the advantages of both. Speed stability experiment and target tracking experiment were carried out on a vibration platform. Results show that compared with conventional controllers, the proposed controller improves the disturbance isolation by 6.28 dB at least. On all accounts, the proposed control system has strong robustness, observably improves the disturbance isolation of the opto-electric platform and can provide guide for engineering applications.

Key words: aircraft control system, square lag-lead control, repetitive control, auto/active disturbance rejection control(ADRC), isolation degree of disturbance
