Design of automobile clutch comprehensive performance detection platform based on Kalman filter

For obtaining the clutch’s operating performance and related characteristics accurately and completely, a platform for testing the automobile clutch comprehensive performance was designed. By adjusting the size of the motor speed, torque and inertia torque plate and the road resistance, the working condition of different models of clutch could be simulated. Thus, a variety of clutch could be tested by using the single device. Due to the big disturbance torque and high requirement of control accuracy, a fuzzy-PID control algorithm was proposed for the rotational speed control. Moreover, Kalman filter was designed to eliminate the random noise and industrial frequency disturbance. Using the industrial computer and PLC as host computer and slave computer, respectively, the interface and data acquisition programs were developed based on the Visual VC++. The experimental results demonstrated that the testing accuracy and efficiency were improved. Moreover, the testing platform worked stably and reliably.
