<p>PURPOSE: To attain the follow-up of a controlled variable to its target value with no delay of response by calculating a manipulated variable for compensation of the delay of response of an operating object based on the future target value, the present and past detected controlled variables and the past manipulated variable which are stored in a storage means as well as the coefficient showing the dynamic characteristics of a controlled system. CONSTITUTION: The control input, i.e., the manipulated variable of a rolling reduction 3 of a rolling mill 1 is calculated by a rolling reduction position controller 10 based on the rolling reduction standard, i.e., the target value and the rolling reduction position, i.e., a controlled variable. The controller 10 consists of a storage means 11 and a control input arithmetic means 12. The means 12 calculates the control input for compensation of the delay of response of the device 3 based on the future rolling reduction standard, the present and past rolling reduction positions and the past control input stored in the means 11 as well as the coefficient showing the dynamic characteristic of the device 3 that is previously decided by an experiment, etc. Thus it is possible to attain the follow-up of a controlled variable to its target value with no delay of response.</p> |
