Abstract
A disturbance auto-rejection control strategy is proposed to realize the high-precision path tracking of large radio telescopes by taking account of the characteristics of nonlinearity, time-varying and disturbances of their fine tuning Stewart platforms, and the readiness of engineering implementation. A disturbance auto-rejection control algorithm and a decentralized control law are developed for this. Experimental results show the feasibility and effectiveness of the presented control strategy and algorithm for high precision path tracking.
