Dynamic Output-Feedback Compensation for Linear-Systems with Independent Amplitude and Rate Saturations
The positive real lemma provides the basis for constructing linear output feedback dynamic compensators for multi-input plants with independent amplitude saturations. Fixed-structure techniques are used to obtain full- and reduced-order feedback compensators along with a guaranteed domain of attraction. These results are then applied to the problem of rate saturation. By using a, feedback-type model, rate saturation is modelled as an amplitude saturation. The closed-loop system with amplitude and rate saturation is then treated as a system with independent ’amplitude’ saturations.
