Abstract

Event-triggered control is developed to reduce the communication load in networked control systems. This means that output or actuator signals are only transmitted over the network when an event-triggering condition is violated which is designed such that a certain control performance can be guaranteed. This paper considers event-triggered control subject to actuator saturation for linear systems. Therefore we present a method to estimate the domain of attraction which represents a contractive invariant set. The contractive invariant set is estimated by an ellipsoid which is determined by solving a linear matrix inequality (LMI) optimization problem. Further a controller synthesis design considering the event-triggering condition in our criterion is given to maximize the contractive ellipsoid. Simulations are given to illustrate the results.
