Abstract:Encounter to the characteristics of nonlinearity, time-varying and large delay constant of the cable-feed system for next generation large radio telescopes and the requirement of easy engineering implementation, an adaptive fuzzy predictive control (AFPC) strategy is proposed to realize the feed tracking for large radio telescopes. The AFPC consists of fuzzy predictor and fuzzy predictive controller, which are trained by using BP algortihm. The simulation results show the effectiveness of the AFPC to guarantee the coarse tracking accuracy requirement for large radio telescopes, which have laid a solid base for the engineering implementation of the high accuracy requirement of the feed tracking for large radio telescopes.
Keywords:fuzzy control  predictive control  large radio telescope  trajectory tracking  large delay
