Abstract
PURPOSE:To prevent plural control means from being mutually influenced and interfered by allowing a model to be controlled to create a variation in the quantity of state of the model being changed by respective control means. CONSTITUTION:A variation in the quantity of state of the model to be controlled based on the inter-stand non-interference control of a tandem rolling mill is estimated by using a control output and the model to be controlled and the estimated value is subtracted from the variation in the quantity of state of the model to be controlled to execute optimum control. The rolling mill rolls a rolled stock 104 by means of a pair of rolling rolls 101-103. The states of the rolling mill are inputted from an adder 50 to address 52-55 through converters 108-110. The output of the adder 52 is inputted to a non-interference control means 56 and the outputs of the adders 53-55 are respectively inputted to an optimum control means 111-113 as state feedback to determine the manipulated variables of actuators 116-118. Optimum control models 59-61 are used for finding out the feedback constants of respective control means 111-113.
