There is realized a control device capable of speeding up an output response without causing deterioration in the resolution of a time-proportional output. The control device controls a control object at a ratio of ON-time to OFF-time for a time-proportional output. The control device comprises a PID computation unit for executing PID computation of deviation between a set value and a measured value from the control object, an integrator for sequentially adding up control output values each representing the result of the PID computation executed by the PID computation unit, an ON/OFF determination unit for determining whether the time-proportional output is turned ON or OFF on the basis of an integrated value of the integrator, and a time-proportional output unit for turning the time-proportional output ON/OFF on the basis of a determination value of the ON/OFF determination unit.
