| Abstract: | According to the characteristics of a large optical telescope by large inertia and nonlinear frictions,an Active Disturbance Rejection Controller(ADRC) was designed to improve the response speed of the servo system.The working principle and basic structure of the ADRC was introduced,the regulation of parameters for the ADRC was given,and each parameter was analyzed imitatively.Finally,the ADRC was compared with conventional PID controllers.Actual results show that the ADRC can not only achieve a higher resp... |
