Abstract

Multiple Model Adaptive Control involves a supervisor switching among one of a finite number of controllers as more is learnt about the plant. Safe Adaptive Control is concerned with ensuring that when the controller is changed in an adaptive control algorithm, the frozen plant-controller combination is never (closed loop) unstable. A controller scheme is proposed that combines these principles and involves a frequency-dependent performance measure based on the Vinnicombe metric . Safe switching is guaranteed to the extent which closed loop transfer function identification is accurate.
