| Abstract: | Given that the large spherical radio telescope (LT) is a flexible feed system with the characteristics of nonlinearity, slow time-variant and large delay, a self-adjusted PID control method based on the parameter BP neural network(NN )controller is utilized to realize feed trajectory tracking. Simulation results show that this controller has a higher tracking accuracy than the conventional PID controller. |
