  • System and method for conditioning a signal
    Patent number: 7078872
    Abstract: A method of conditioning a signal being communicated between a system to be controlled and a controller may include monitoring an actual output signal and conditioning the actual output signal. The method also includes determining the difference between the actual output signal and the condition signal and causing the actual output signal to be filtered based on the relationship between the difference between the actual output signal and the conditioned signal.

  • System and method for controlling a motor
    Publication number: 20040085034
    Abstract: A method of controlling a motor may include controllably operating a motor with a desired input command to attain a desired output response of the motor, monitoring an output of the motor, and determining a difference between the monitored output and the desired input command. The method may further include establishing a deadband around the difference and determining a torque command based on a relationship between the difference and the deadband.
