Event-triggered control for p-normal uncertain nonlinear systems

When dealing with microprocessors with limited resources and networks with limited bandwidth, the research of event triggering technology becomes more and more important. In order to save communication resources, this paper is concerned with the event-triggered control problem for a class of p-normal uncertain nonlinear systems with unknown growth rate. At first, an event-triggered controller is designed for the nominal system by adding a power integrator technique. Then, a novel dynamic gain is introduced into the proposed event-triggered controller to render lower-triangular uncertain nonlinear systems globally asymptotically stable. At the same time, Zeno phenomenon is excluded. Finally, the proposed method is extended to event-triggered control of p-normal upper-triangular uncertain nonlinear systems. A practical circuit system and a numerical simulation are given to illustrate the effectiveness of the proposed method.
