This paper presents an indirect adaptive control scheme for nominally stabilizable, but possible non-controllable, continuous and time-varying systems with unmodelled dynamics. The control objective is the adaptive stabilization of the system. The scheme includes several estimation algorithms and a supervisor which selects the appropriate estimator keeping it in operation during at least a minimum residence time.
Keywords: Adaptive control, supervisory control, robust stabilizability, time-varying plants, estimation algorithms, pole assignment
