Intelligent Control of a Servo-Motor-Driven Shock Absorber Performance Tester

This chapter describes a project on the driving and controlling system of an automotive shock absorber tester. The system structures and key parameters are designed followed by the analysis of function partitioning and collaboration of a host personal computer (PC) and the controller. The communication protocol between controller and host PC is developed. Then, the structure and the flow chart of the controller program are presented. Finally, the performance test result using the tester with the developed drive system is given and compared with a qualified tester, which shows the accuracy of the new system.
