Abstract
The effects of observers on robust linear feedback controllers are studied. Sufficient conditions are obtained that guarantee full recovery of the allowable uncertainty bounds attainable by full state feedback. The effects of the resulting high gain observers on the disturbance rejection bounds are also studied. It is shown that full recovery of the uncertainty bound leads to possible large degradation in disturbance rejection. However, if there is only additive plant disturbance and no measurement disturbance, this degradation can be prevented.Keywords
