Abstract:
Systems and methods for operating a motorized system. The methods comprise by a circuit: receiving a first position signal generated by a gimbal resolver coupled to a load, a second position signal generated by a first motor encoder coupled to a shaft of a first motor, and a third position signal generated by a second motor encoder coupled to a shaft of a second motor; converting the second and third position signals into a velocity signal specifying a scaled velocity of the load; converting the velocity signal into a fourth position signal specifying a position of the load; combining the first position signal and the fourth position signal to generate a fifth position signal representing a stable position of the load; and using the fifth position signal to control operations of the first and second motors.
