Abstract
A method and system of process control comprising in combination a feed-back control in which a deviation of a controlled variable with reference to a target value is applied to a velocity type controller and a manipulated variable is determined in accordance with the output of the controller and a feed-forward control in which a disturbance is detected and a disturbance compensation is determined and added in determining the manipulated variable to counteract the effect of the disturbance. A static compensation component and a dynamic compensation component of the disturbance compensation are separately determined in accordance with the detected disturbance, and the static compensation component is converted to a velocity type signal, and added to the output of the controller to obtain a first sum. The first sum is converted to a position type signal, and added to the dynamic compensation component to obtain a second sum, in accordance with which the manipulated variable is determined.
