ABSTRACT:
A two degree of freedom PID controller which includes a setpoint filter for performing a derivative operation on a process disturbance signal in accordance with a setpoint value and a control value of a controlled system, thereby outputting a setpoint signal, a PI-control operation device for determining a deviation between the setpoint signal and the control value, and performing a PI-control operation on the deviation, thereby outputting a manipulative signal, and an adder for adding the process disturbance signal to the manipulative signal output by the PI-control operation device, thus obtaining a sum signal, and for supplying the sum signal to the controlled system.
