Abstract:
PURPOSE:To attain the highly accurate ON/OFF control of a feedforward switch at a high speed despite the unknown or varied characteristic of a machine system to be controlled. CONSTITUTION:When a feedforward switch 4 is kept OFF, a machine 1 works with input of the output of a PI control part 2 which is calculated based on the value obtained by subtracting the answer Y (k) of the machine 1 from the target value Yd (k). When the switch 4 is turned on, the output U* (k) of a model identifying part 5 is added to the output of the part 2. Based on these added value, the machine 1 works. The ON/OFF control of the switch 4 is attained with the comparison performed between the value obtained by subtracting the output U* (k) from the value U (k) which is inputted to the machine 1 and the prescribed value.
