Claims

[Scope of utility model registration request]

(1) An arithmetic circuit that calculates a control signal for controlling the controlled system based on a preset setting value and a feedback signal fed back from the controlled system to bring the value of the feedback signal close to the setting value. and one or more output circuits that calculate a signal of a desired format from the control signal and supply it to the controlled system.

(2) the output circuit comprises a comparison circuit that compares the control signal with a preset constant setting signal;
When the control signal input to the comparison circuit is higher than the setting signal, a first signal is output, and when the control signal is lower than the setting signal, a second signal is output. A controller according to claim 1 of the patent registration claim.

(3) The output circuit includes a comparison circuit that compares the control signal with a continuous waveform wave having a predetermined period set in advance, and a portion where the waveform wave input to the comparison circuit is higher than the control signal. The controller according to claim 1, wherein the controller outputs a third signal at a portion where the waveform is lower than the control signal, and outputs a fourth signal at a portion where the waveform is lower than the control signal.

(4) The controller according to claim 1, wherein the output circuit comprises a voltage/current conversion circuit, and the voltage/current conversion circuit generates a current signal according to the control signal.
