Patent ID: 11588429

Abstract:
A motor control system for controlling a motor having multiple coils, includes a motor control circuit for providing control signals for controlling a motor, such as PWM signals. A motor drive circuit is coupled to receive the control signals and is configured for providing current drive signals to the multiple coils of the motor. Circuitry measures a plurality of signal values that are reflective of the level of the current drive signals provided to the multiple coils of the motor. Selection circuitry coupled to receive the measured current signal values is configured to dynamically select certain current signal values from the measured plurality of signal values and is further configured to exclude at least one of the current signal values that is indicative of a possibly erroneous or unreliable value. Calculation circuitry is configured to use the selected signal values to calculate a value for the excluded current signal value and the motor control circuit uses the measured and calculated current signal values for providing the control signals for a motor.
