Adaptive Control in the Presence of Input Constraints

This paper deals with the problem of adaptively controlling a linear time-invariant plant in the presence of constraints on the input amplitude. We introduce a new algorithm which ensures that the adaptive controller leads to bounded solutions when the initial conditions of the adaptive system lie within a compact set. The results are applied to the problem of manipulation using compliant fingerpads.
