Abstract
In this paper, the performance deterioration of optimal regulators caused by the introduction of Kalman filters as state estimators is investigated. It is shown that, in the ease of single-input single-output systems, the performance deterioration cannot be made arbitrarily small unless the optimal control law can be implemented by direct output feedback.Keywords
