An apparatus and method for controlling a device using pulse signals. In the apparatus and method, a two-stage control is used to generate pulse signals, which can be a PWM signal, a pulse signal including a PWM signal with a sleeping time, or a PDM signal. The two-stage control includes a second stage control, which generates pulse signals according to parameter values generated periodically by a first stage according to a target value and feedback sensing values. The two-stage control can be used in decreasing perturbation in a closed-loop control and accurate open-loop control.
