Finite‐time event‐triggered bumpless transfer control for switched systems

Abstract

AbstractThis study centers on the issue of finite‐time event‐triggered bumpless transfer (BT) control of switched systems. The aim is to suppress the undesirable control jumps at both switching and triggering time, and guarantee the finite‐time stability of switched systems. First, the property of BT is described from its original intention. Then, by co‐design of an improved switching function, an event‐triggered strategy combined with a series of controllers to achieve this objective. Also, the Zeno behavior is excluded. Further, a criterion to guarantee the BT property and the finite‐time stability under event‐triggered mechanism is established. Finally, a turbofan engine control system is taken as an example to testify the validity of the presented control scheme.
