A novel adaptive sliding mode control is proposed to guarantee high precision and robustness of servo system of rocket launcher. An improved PID switching function is designed to smooth control input, meanwhile Chebyshev neural network is adopted to identify the system’s Jacobian information, and parameters of controller can be acquired by self-tuning law which can be derived by Lyapunov theory. Simulation results show the control input is chattering-free, and both load disturbance and parameter perturbation can be compensated.

According to the requirement of high precision and high speed in an AC servo system, based on sliding mode control theory, a cascade control is put forward. Sliding mode controller of the speed loop is applied to reduce the system steady state error and increases system response speed, and the sliding mode control of the position loop is applied to improve the system dynamic tracking accuracy and system robustness. According to the simplified mathematical model of the position loop and speed loop, system control law is derived. Experiment results show that the proposed sliding mode cascade controller can guarantee the dynamic performance of the servo system.
