ABSTRACT:
In a method and a system for process control comprising in combination a feed-back control in which a manipulated variable is determined in accordance with a deviation of a controlled variable with reference to a target value and a feed-forward control in which a disturbance is detected and a disturbance compensation is determined and used in determining the manipulated variable to counteract the effect of the disturbance, when the control is in a steady state, disturbance compensation is adjusted in such a manner that the difference between the disturbance compensation and the manipulated variable is reduced.
