基于部分状态反馈信息的切换控制器设计OA

The inability to obtain the complete feedback and utilization of system state information is a common problem in practical control systems.The switching idea can effectively solve the problem in stabilizing the controlled system caused by insufficient partial state feedback information and limited control input energy.Therefore,this paper proposes a strategy that combines partial state feedback with the switching control idea.Specifically,for a second-order linear controlled system,two parameterized partial state feedback controllers are designed for the controlled system first,and then the switching line is calculated based on the principle of maximum energy drop to design the appropriate switching rule and switching controller.For a third-order linear controlled system,the Pade reduction method is first used to convert it into a linear second-order system,and then an appropriate switching controller is designed for the simplified model.Finally,the switching controller of the original third-order linear controlled system is obtained based on the projection matrix method.Simulation results show that the switching control strategy proposed in this paper can make the state of the controlled system converge rapidly to the equilibrium point.
