<p>PURPOSE:To securely control a high-precision shape by evaluating a plate shape and a plate thickness on the outlet side regarding a specified synthetic evaluation function, requiring a manipulated variable of each actuator to minimize this synthetic evaluation function value and controlling each actuator simultaneously based on this manipulated variable. CONSTITUTION:The shape and thickness of the plate on the outlet side are evaluated synthetically by the synthetic evaluation function, the manipulated variable of each actuator 11 - 13 minimizing the value of this synthetic evaluation function is always required, each actuator 11 - 13 is controlled simultaneously based on the manipulated variable obtained to control the plate shape of the rolled material 1, therefore, the shape of the rolled material need not be identified and, besides, when the actuator 12 for controlling the plate shape is manipulated, the change of the rolling down position of the roll which is made by estimating the change of the plate thickness is prevented from causing a vicious circle such as generation of another change of shape and drastically precision shape can be controlled securely.</p> |
