The Optimal Control Design and Simulation of Actuator Electric Loading System
Considering the problem of surplus torque disturbance existed in the UAV actuator electric loading system,we proposed a compound control strategy combining linear quadratic optimal control with PID control for realizing the load torque control of the actuator electric loading system.The state space model was established with skillfully selected state variables for the electric loading system,and the optimal control law was obtained,which suppressed the disturbance caused by actuator movement effectively.Simulation result shows that the control strategy has good control precision and anti-interference capability.Compared with the compound control strategy combining CMAC neural network with PID,which is commonly applied in electric loading field,the proposed method is simpler and has smaller amount of calculation,faster simulation speed and smoother output.
