<p>PURPOSE:To improve the control performance and to secure the adaptability of a system by collating the value obtained by applying a prescribed proportional operation to a water level major loop and a control command to control the water to keep a fixed level. CONSTITUTION:A proportional element 26 applies a prescribed proportional operation to the deviation output between the detected water level and the target level given from a collation circuit 10. At the same time, a prescribed differential operation is applied to said deviation output by a differential element 28. Then the output of a servo motor 16 is controlled in response to the own flow rate D(S) based on the collation output given from a collation circuit 30 in which said operations are used as a deviation input. Thus the water of a water tank 20 is kept at a fixed level.</p> |
