Abstract
A method for compensating for dead time non-linearities in a pulse width modulation (PWM) controlled device including obtaining a motor data signal, generating a duty cycle of the motor voltage responsive to the motor data signal, determining a compensation value responsive to the duty cycle of the motor voltage, generating a compensated duty cycle in response to the compensation value and the duty cycle of the motor voltage and introducing the compensated duty cycle to the PWM controlled device. In addition, a medium encoded with a machine-readable computer program code for compensating for dead time non-linearities in a pulse width modulation (PWM) controlled device, the medium including instructions for causing controller to implement the aforementioned method.
