Abstract :
The speed controller and the flux controller are designed separately in crane lifter system based on the control theory of sliding mode variable structure, the chattering are weakened by adopting improved index reaching law, and the different value of each parameter of controller that affects the control effect is analyzed . The simulation results show that sliding mode controllers have a faster response, smaller overshoot, higher control precision, stronger robustness and so on, especially adapt to high-order, non-linear, strong-coupling, multi-variable system.
