In a feedback control system for providing a pulse width modulated control signal for feedback controlling a motor or other device in accordance with control error data, control data produced according to the control error data and previously stored rounding error data are added together, and the sum of the control data and rounding error data is in turn rounded off, while the rounding error data is stored in a register, memory, or the like. The pulse width modulated control signal is then produced according to the rounded-off data.
