摘　　要：探讨了滑动模态变结构控制(滑模控制)设计原则,设计了一种滑模控制器,实现了两输入两输出非线性液位系统控制,并用组态王(Kingview)编制该控制软件,解决系统难于控制和抗扰动的问题.在线运行,体现了滑模变结构控制自适应能力强,动态、静态品质优良,鲁棒性好等优点,与传统PID控制进行比较,证实变结构控制的优越性.Design principle of a sliding mode variable structure controller for a nonlinear system of two inputs and two outputs in order to control liquid level is inquired. The sliding mode controller is designed. The system software is programmed by KINGVIEW. Running it online, it is proved that the sliding mode variable structure is able to respond quickly,invariant in systemic parameters and external disturbance,and able to keep the system at a stable state. The robustness of the system is ensured. Comparing with PID controller, the sliding mode controller has superiority.
