Abstract

This paper concerns the problem of guaranteeing the stability of dynamic systems that can undergo mode transitions caused by external events. The mode transitions can include a finite-duration transient phase. Assuming the system is designed to be stable in each mode, with associated regions of stability, the problem is to compute the region of states in the pre-transition mode for which it can be guaranteed the system will be in the region of stability in the post-transition mode. We call this region in the pre-transition mode the virtual stability region. Methods for computing the virtual stability region are discussed and illustrated for a small power system example
