Event-triggered feedback control for discrete-time piecewise affine systems subject to input saturation

ABSTRACT In this paper, the problem of event-triggered control for discrete-time piecewise-affine system is investigated. An optimisation problem for minimising the upper bound of quadratic cost function for quantifying the control performance is formulated in the form of linear matrix inequalities (LMIs). The unique state-feedback control gain under the event-triggered strategy can be obtained by solving the LMIs optimisation problems. Comparisons by the simulations are given to demonstrate the advantages of the proposed approach, where the number of control input updates is reduced, while the control performance is still guaranteed.
