Design Of Event Trigger Mechanism For Nonlinear Network Control System With Unknown Measurement Sensitivity

This paper investigates the stability of a class of nonlinear systems with unknown measurement sensitivity and the problem of periodic event-triggered output feedback control.Firstly,an observer based on system output and control input is designed for such nonlinear systems with unknown measurement sensitivity,the state of the system is estimated,then the controller is designed by using the estimate of system state,the global asymptotic stability condition of the system is obtained,and the effectiveness of the controller design is verified.Secondly,in the network environment,the periodic event triggering transmission mechanism is considered.By selecting appropriate control gain and sampling period,the global practical stability of the nonlinear system with unknown measurement sensitivity can be guaranteed.Finally,the numerical analysis is given to verify the correctness of the theoretical analysis.
