Abstract
A system for monitoring pulse width modulation (PWM) duty operation execution for motor control, which can detect whether or not the PWM duty operation execution used for torque and speed control of a motor is performed normally within an interrupt execution timing, and perform failure diagnosis depending upon the detected result, thus enhancing stability of motor control.
