Adaptive Event Triggered Control of Nonlinear Systems With Controller and Parameter Estimator Triggering
In this note, the event triggered adaptive control for a class of uncertain nonlinear systems is considered. Unlike the traditional adaptive event triggered control, the controller and parameter estimator are event triggered simultaneously. Asymptotical convergence of stabilization error is guaranteed. To solve this problem, we design a set of event triggering conditions, which is updated for each triggering. At the same time, the input to state stable assumption is not needed. It is shown that the proposed control schemes guarantee that all the closed loop signals are globally bounded and the stabilization error converges to the origin asymptotically. Simulation results illustrate the effectiveness of our scheme.
