In this paper design of switching controllers for linear systems is considered. The controllers are LQ controllers with prescribed degree of stability and switching sequence is determined by minimization of suitable defined priority function. Hybrid controller is developed based on system performance. In the form of theorem is proved: equilibrium point of the hybrid system is exponentially stable and performance of system is no worse then the best non-switching strategy.
Keywords: LQ controller, degree of stability, hybrid control, priority function, exponential stability
