基于无线传输的非线性网络控制系统的模糊控制

考虑控制器与被控对象之间采用无线传输,且被控对象为非线性模型的一类网络控制系统,对其设计了稳定的模糊控制器。首先基于T-S模糊模型将对象线性化,并利用模糊主导子系统和主导控制规则,简化了模糊控制器的设计。其次,将闭环控制系统方程等效为与无线传输跳数相关的离散切换系统,并证明了闭环系统的稳定性。最后,通过一个仿真例子验证了文中方法的有效性。

Abstract：

Considering a class of networked control systems using wireless transmission between the controller and the controlled object,and with nonlinear controlled object,the stable fuzzy controller was designed.Firstly,based on T-S fuzzy model,the object was linearized.And the design of the fuzzy controller was simplified by using the fuzzy dominant subsystem and the dominant control rule.Secondly,the equation of the closed-loop control system was equal to the discrete switched system related to the hop count of the wireless transmission.Finally,a simulation example was given to demonstrate the effectiveness of the proposed method.
