Adaptive Robust Pole Placement - An Alternate Approach

This paper proposes an alternate approach for adaptive robust control of linear systems with structured, wide-ranging parametric uncertainties. The overall scheme consists of two steps; namely, off-line design of a robust observer for the partial states of the system, and design of an on-line adaptive pole placement scheme. It is shown that by using this approach, both direct as well as indirect adaptive pole placement can be achieved. Proofs of stability of the schemes are also given.
