| Abstract: | This paper describes the design theory and methods of the linear quadratic optimal state feedback controller. The conditions for the existence of optimal observer and observer-based optimal state feedback control theory are given. Taking inverted pendulum as a controlled object, I made some Maflab simulations, discuss the effect of the parameters Q and R on the optimal control system. Through comparing the optimal controller with the PID controller, I got the result that the optimal controller is better than PID controller. |
