【Abstract】 The Simulink simulation speed and effect are decreased because of the uncontinuous functions in the uncontinuous systems, such as sliding mode variable structure control systems, optimal control systems and so on. The reasons caused the problem were analyzed in detail and corresponding resolving methods were also developed. Based on the presented methods, the Simulink simulation on variable structure control of an overhead crane system was studied, and the simulation results demonstrate the effectiveness of the prompted Simulink simulation schemes. Finally, some suggestions on the problem were summed up.更多还原
