Abstract
A fuzzy sliding mode controller was designed to solve uncertainty problems such as nonlinear sea wave disturbance and parameter time variant in the working process of a naval gun loading device. On the basis of building a system dynamics model for this device, the universal approximation property of the fuzzy system was used to realize the adaptive approximation of control parameters, and the Lyapunov analytical method was used to export the fuzzy adaptive laws to prove the stability of this method. Simulation results show that the comprehensive control performance of this control strategy is superior to the control effect of PID method. Specifically, it is able to remain the system with a stability performance under sea wave disturbance and parameter variant, and provides strong capabilities of resisting disturbance and tracking positions.
