【摘要】 为了解决基于TS(T akag i-Sugeno)模型的模糊控制方法在高阶单输入单输出(S ISO)非线性系统模糊控制中出现的“维数灾”问题,采用由作者研究组提出的多输入单输出(M ISO)典型模糊控制器,提出了模糊滑模控制方法,并且证明了闭环非线性系统的全局渐近稳定性。另外,当非线性系统存在模型不确定性时,只要将控制式略加修改,仍能保证闭环非线性系统的全局渐进鲁棒稳定性。仿真试验表明,该模糊滑模控制方法不仅设计参数少,设计步骤简单,具有良好的控制性能,并且可以有效地避免了维数灾问题。更多还原

【Abstract】 Fuzzy control methods based on the Takagi-Sugeno fuzzy models do not work well for higher-order single-input single-output nonlinear systems.A fuzzy sliding-mode control method using an multi-input single-output fuzzy controller was developed to provide closed-loop global asymptotic stability of the controlled system.In addition,small modification of the control formula gives effect controll of systems with model uncertainties to ensure the robust stability of the closed-loop system.An example of the simple design procedure with few design parameters shows the excellent control performance for higher-order control problems.更多还原
