Abstract

PURPOSE:To realize the regulating with fine accuracy by executing simultaneously in parallel a rough adjustment control by an opening adjusting operation of a large valve, and a fine adjustment control by an opening adjusting operation of a small valve. CONSTITUTION:A flow rate of a fluid flowing in a fluid carrying system becomes a regulated variable, a valve opening adjusting operation is executed so that this flow rate follows up a fluctuated object value, and a flow rate variation portion is regulated by distributing it into a rough adjustment control by an opening adjusting operation of a large valve 3 and a fine adjustment control by an opening adjusting operation of a small wave 4. As for its distributing method, in case of a repeated control flow, the distribution is executed in a state that an opening adjusting manipulated variable of a small valve in the control flow of each time is allowed to have a margin, and when its margin does not exist in the small valve 4, the distribution is executed so as to compensate a portion for generating its margin by an opening adjusting manipulated variable of the large valve 3. Accordingly, the range of the flow rate which can be controlled extends over a wide range from '0' to the sum of each maximum flow rate of the large valve and the small valve, and also, as for the control accuracy which follows up the flow rate target value in its range, the accuracy being equal to the control accuracy of the small valve is secured.
