A controller according to an embodiment comprises: a feedback control unit which receives an output signal of a control target device via a first input terminal, receives a reference signal via a second input terminal, and outputs a control signal arising from a difference between the output signal and the reference signal; and a clamp circuit unit which selectively operates depending on a size of the control signal outputted from the feedback control unit to limit the size of the control signal to a certain level. |
