目標値フィルタによる2自由度一般化最小分散制御に関する一考察

抄録

In order to improve the response property of the closed-loop control system constructed by generalized minimum variance control (GMVC), in general, the control-weighting polynomial included in the cost function is adjusted. But, the tracking response to the reference-signal and the response property for disturbances are changed together when the control-weighting polynomial is tuned.
A method solving this problem is a two-degree-of-freedom GMVC. In this paper, we propose a two-degree-of-freedom GMVC with the reference-signal-filter. On the other hand, we propose the control system allowing the reference-signal-weighting to be a rational function in the conventional control structure. This system can set up the feedback property and the tracking performance independently.
