摘要
文中针对多输入、多输出的非线性三罐耦合系统,提出了一种基于积分滑模的液位控制方法,该方法能够使系统底部储液罐的液位在动态中达到设定的目标点并保持稳定。在控制器设计过程中,采用积分滑模技术,其引入了滑模变量函数,使得系统可以免受来自内部及外部干扰的影响。通过李雅普诺夫方法,从理论上证明了滑动平面的稳定性。仿真结果验证了该方法对于三罐耦合系统液位控制的有效性。
In this paper,a liquid level control method based on Integral Sliding Mode Control(ISMC)is proposed for multi-input and multi-output nonlinear Three Tank Coupling System(TTCS).The method could enable the liquid level of the tank at the bottom of the system to reach the set target point and keep stable in the dynamic state.In the process of the controller design,the ISMC which adpot the sliding variable function is used to keep the system from internal and external interference.The stability of the sliding plane is proved theoretically by using Lyapunov method.The simulation results verify the effectiveness of the proposed method for the level control of TTCS.
