摘要：

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