Fuzzy Sliding Mode Control of Ammunition Lifting Device Based on Disturbance Observer
A fuzzy sliding mode control strategy based on a disturbance observer is proposed to address the uncertainty caused by load changes and external disturbances in the position control process of a new ammunition lifting device.A disturbance observer is introduced for online estimation and feedforward compensation of the composite disturbance.As the uncertainty of the system parameters makes it difficult to model the system accurately,fuzzy logic is used to approximate the mathematical model so as to establish an equivalent control law,which greatly reduces the difficulty of controller design.Simulation results show that the designed control strategy is able to control the position of the ammunition lifting device accurately in the presence of external disturbances,and has good robustness.
