Design method for output feedback controller of linear switching system

Abstract

The invention discloses a design method for an output feedback controller of a linear switching system. The method comprises the following steps of step (1), modeling the state of a controlled objectof a class of activated linear switching systems needing to be designed; step (2), modeling the output of a dynamic output feedback controller needing to be designed; step (3), defining dynamic eventtrigger conditions of the controlled object and the dynamic output feedback controller; step (4), designing a switching law of the linear switching system; step (5), designing conditions for the switching system; and step (6), giving a minimum triggering time interval taup of a sensor-controller channel and a minimum triggering time interval tauc of a controller-actuator channel. Compared with theprior art, the output feedback controller of the linear switching system designed by the method of the invention ensures the stability of a closed-loop system; and furthermore, the number of times oftriggering is further reduced, so that network resources are more effectively saved.

Description

technical field [0001] The invention belongs to the field of controller design, in particular to a switching system output feedback controller designed based on a dynamic event trigger mechanism. Background technique [0002] In recent years, switching systems have been widely used in system modeling and analysis of industrial processes such as transportation systems, chemical production, power systems, aircraft control systems, and network control. Its important theoretical value and practical significance have attracted more and more people. scholars have studied it. In addition, the state of many actual control systems is often unmeasurable. At this time, the method of state feedback cannot be used for controller design. In order to stabilize the system, a more practical output feedback controller must be used. [0003] The application of network control systems in modern society is gradually increasing, and network transmission is becoming more and more extensive. Wirel...
