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

This 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.
