Abstract :
In this paper, according to the mathematical model of control stabilization loop and the characteristics of operating conditions of stabilized platform of shipborne weapons(SPOSW), a sliding mode variable structure control (SMVSC) is proposed. It is a time-varying, non-linear system, so it is difficult to meet the control performance with the classic PID. Compared with classic PID controller, simulations show that the SMVSC can not only meet the static and dynamic requirements, but also improve the robustness and disturbance attenuation of the system remarkably. At the same time, the index reaching law is taken into account to overcome chattering problem.
