Stable and real-time scheduling of a class of hybrid dynamic systems. (English) Zbl 0920.90078

Summary: Based on some practical engineering problems arising from process control and space-structure control, this paper studies a class of hybrid dynamic systems in which \(N\) plants are controlled by a central controller in sharing time manner, where the plants are described by differential equations and the controller works according to the mechanism of discrete events. An event feedback strategy is suggested to be a scheduling policy such that one and only one plant among \(N\) plants is chosen to be controlled at any time. Some conditions of asymptotical and exponential stability are then given and an exponential upper bound of state’s norm is also estimated for the event feedback scheduling strategy. An algorithm based on event feedback strategy is presented to determine the control laws of the plants to meet the given performance. An example follows to illustrate the application and effect of the results.
