ABSTRACT:
There is provided a method of controlling a two-degree-of-freedom control system for controlling a controlled object. The method includes the steps of generating a first signal for feedforward control using a target value and generating a second signal for feedback control using an output signal from the controlled object. The method further includes the steps of outputting a plurality of the first signals while the second signal is outputted once, and controlling the controlled object by using the first signal and the second signal. In the present invention, plurality of the first signals include signals with different time widths.
