Compensation of switching effects in hybrid event-based control systems

Abstract

This paper introduces event-based control as a means to improve the behaviour of feedback loops with switching controllers. It investigates hybrid event-based control systems where the event-based part of the controller affects a continuous control loop. Its task is to adjust the operating point of this control loop to changing operation modes of the overall system. The paper introduces a control input generator into the event-based path of the system and presents a method for its design. The main aim is to compensate undesirable switching effects of the event-based part on the continuous control loop. The main result of the paper is a set of conditions ensuring that the overall system is stable, asymptotically tracks a piecewise constant reference signal and is robust with respect to model uncertainties and disturbances.
