| Research Abstract |
Disturbances in control theory are exogenous signals that cannot be manipulated artificially. It should be noted that disturbances are not always harmful for control objective. This project aims at developing a new systematic design method for disturbance utilization controllers. It is pointed out that a controller designed by the disturbance cancellation technique can be regarded as a disturbance utilization controller where the usage of the friendly disturbance is apparent. The optimal disturbance cancellation controllers are constructed using a non-standard quadratic performance index which explicitly requires the disturbance cancellation. As a systematic tuning method of the optimal controllers, the extended version of the classical loop transfer recovery method is proposed, the effectiveness of which is confirmed by several design examples.
