Co-simulation of Dynamic Surface Sliding Mode Control for Elevation Equilibrator Electro-Hydraulic System of Truck-Mounted Howitzer

This paper proposes a DSSMC (dynamic surface sliding mode control) strategy to track the desired angle for one elevation equilibrator of truck-mounted howitzer. Dynamic surface control is introduced to solve the problem of nonlinearity, unmatched external loads, parameters uncertainty and differential explosion caused by backstepping method. The stability is proved by Lyapunov method and the performance of this control strategy is verified by the method of co-simulation with AMESim and MATLAB. The co-simulation results show that, compared with PID control strategy, DSSMC strategy has better tracking accuracy and rapidity.
