COMPUTERIZED MODEL PARAMETERS ADAPTIVE CONTROL SYSTEM FOR HYDRAULIC POWER SHIFT TRANSMISSION DURABILITY TEST BOARD

This paper presents a computerized automatic control and data legging system, embedded in a hydraulic power shift transmission durability test beard, as well as its operation performance. By inference of the diesel engine’s mathematical model proposed by J. I. Soliman, the parameters and the expression of the model are derived, and a practical and quite accurate mathematical model of hydraulic moment transmission is obtained. The developed computerized control system, with adaptive model parameter compensation, is able to adapt to the change of working condition of the test beard and will regulate the model parameters in real-time, so that the speed regulating process possess a good static and dynamic accuracy. The on-site test results demonstrated the success of the computerized control system.
