Abstract
A wheel slip controller for a locomotive is disclosed that utilizes PID controllers to control the traction wheels during normal locomotive operation. The controller monitors several independent wheel slip indicators to provide rapid detection of excessive wheel slip. Upon detecting excessive traction wheel slip, motor control from the operative PID controller is suspended and a wheel slip compensator assumes command of the traction wheel drive motors. The wheel slip compensator then dynamically compensates the motors depending upon the amount of wheel slip that is detected. Once the wheel slip condition has been corrected, control of the traction motors is transferred back to the interrupted PID controller.
