性能驱动下的切换系统事件触发控制及其应用

This project studies the performance driven event-triggered control for switched systems and its application to the control design of hypersonic vehicle/engine regulation and protection. The main contents include: First, study the stability analysis method of switched systems under the coupling of event triggering and system switching; Seek the causes and the avoidance measures of Zeno sampling in switched systems; Establish a passive design method of switched systems event-triggered control driven by network transmission performance. Then, look for the internal mechanism of interaction between system switching and event triggering; Taking triggering and switching as active control behaviors and design tools, obtain an active design method of switched systems event-triggered control driven by network transmission performance. Moreover, focusing on the switching control performance, investigate the switched systems event-triggered control for ensuring robustness, multi-asynchronous switching stability and switching transient performance. In addition, build a hypersonic vehicle model platform based on the multi-safety limits of the engine, and conduct the corresponding control design and verification. ..The research results will provide important theoretical basis for revealing the interaction mechanism of continuous dynamic, discrete switching and event triggering and their impact on the system performance. The results will also enrich and develop the existing switched systems theories, and provide a feasible technical support for the solution to practical control problems such as hypersonic vehicle safety protection and integrated design of computation, communication and control.
