摘要

This paper presents an indirect adaptive control scheme with pole-placement which is applicable to continuous linear time-invariant systems of unknown parameters even if the plant is not inversely stable and/or not controllable. The only assumption about the system is the property of stabilizability of the plant. The scheme is a pole-placement type while leading to performances very close to those of model-following schemes without requiring the plant inverse stability assumption. The control objective is that the plant output should asymptotically track a reference signal, given By an arbitrary stable filter, under a small stationary tracking-error in some prefixed frequency Interval, while ensuring robust closed-loop stability.
