Title:
変調アルゴリズムを用いたプラントの制御装置
Document Type and Number:
Japanese Patent JP4459674
Kind Code:
B2
Abstract:
There is provided a control method for sufficiently compensating the non-linear characteristic for a plant having a strong non-linear characteristic and satisfying the follow-up and stability for a plant having a large control amount fluctuation. There is provided a plant control device using modulation algorithm. The control device includes: means for calculating a temporary control input for controlling the plant output to a target value; means for dividing the temporary control input into a plurality of components; means for modulating at least one of the components; and means for adding the modulated component to another component so as to generate a control input. Thus, it is possible to minimize the input fluctuation caused by modulation while maintaining the compensation ability of the non-linear characteristic such as plant friction and hysteresis attributed to the conventional modulation algorithm. Accordingly, even in a plant in which the temporary control input is greatly changed, it is possible to prevent oscillation of the output, thereby improving the controllability.
