On the one hand,with the continuous development of society,automation control theory continuously faces a variety of novel challenges.The traditionally monomodal control system has not been already described behavior of sophisticated system and has not been already obtained satisfactory control effect.Therefore,people started investigating modeling and control of the complex system.From the point of system and control,switched system is a important model of investigating complex system.It draws attention of the mainstream researchers in the world.On the other hand,event-triggered control strategy can solute questions of communication limited,network congestion,waste of resources and the like,which is employed in network control systems.And this strategy can reduce updating frequency of controller so that it can increase the life of system.By applying event-triggered strategy,event generator and switching controller are co-designed for stabilizing continuous-time switched linear systems,discrete-time switched linear systems and LTI system.Analyzing L2 gain performance of switched systems based on event triggered strategy.It contains the following works:First,by using piecewise Lyapunov function method,average dwell time and self-triggered control technology,we investigate the exponential stability of continuous-time switched linear systems under event-triggered control.A sufficient condition on the existence of the switching control law and the event generator is established.Then,we illustrated the lower bound between any two consecutive task release time is strictly positive.Moreover,we analyze weighted L2 gain performance of continuous-time switched linear systems.Simulation is applied to illustrate the feasibility and efficiency of results.Second,by using piecewise Lyapunov function method,average dwell time,LMI and self-triggered control technology,we investigate the exponential stability of discrete-time switched linear systems under event-triggered control.A sufficient condition on the existence of the switching control law and the event generator is established.Then,the next event-triggered instant is confirmed.Moreover,we analyze weighted and non-weighted L2 gain performance of discrete-time switched linear systems.Simulation result illustrates the feasibility and efficiency of the proposed method.Finally,switched event-triggered dynamic output feedback control is investigate.We design a class of switching signal and search for the co-design condition of event generator and hybrid controller such that the system is exponentially stabilize under the joint work of switching law,control law and event-triggered conditions.Compared to time-triggered control,it saves the resource.Simulation result illustrates the feasibility and efficiency of the proposed method. |
