ABSTRACT:
Servo motor controls are disclosed for passivation in the event of failures with at least two independent control paths and validation of positional information. A sensor assembly generates signals indicative of the position of the motor rotor, and a signal validation detector is used to validate the generated signals and inhibit rotation of the motor rotor when the sensor assembly generates an invalid signal. A first information processor is provided in communication with the sensor assembly for receiving the generated signals to establish an A Lane decision-making channel control path to the PWM interface, and a second information processor is in communication with the sensor assembly to establish a B Lane decision-making channel control path to the PWM interface. Control logic provided with a PWM interface also inhibits rotation of the motor rotor when a decision from the A Lane differs from a decision from the B Lane. The commutation signal detector provides a state machine to validate the commutation and ensure the validity of signals indicating the position of the motor rotor from the sensor assembly.
