Abstract
An all digital control method for motor drivers eliminates physical motor current sensing. The motor and the driver are modeled to estimate the actual current and the estimated current is used to perform motor control. This provides simplified driver circuitry. Driver non-linearity due to driver dead time may be compensated and minimum driver on times are accommodated while providing good waveform fidelity, minimized motor heating and increased motor system damping.
