Abstract:
Systems for compensating for force fighting in multi-actuator systems are provided. A drive controller unit comprises a first feedforward controller in communication with a first actuator and configured to receive a drive command signal. A first feedback regulator is configured to output a first feedback input into the first feedforward controller, and to receive as input a first actuator position and a first actuator force. The drive controller unit further comprises a second feedforward controller in communication with a second actuator and configured to receive the drive command signal. A second feedback regulator is configured to output a second feedback input into the second feedforward controller, and to receive as input a second actuator position and a second actuator force. The drive controller unit utilizes both feedforward controllers and both feedback regulators to minimize force fighting while driving a common aileron.
