Performance Analysis of Skyhook Damping Semi-active Control Algorithm Considering ECR
摘要
Abstract
In order to realize the energy self-supply of a composite electrical-magnetic suspension (CES), which is constituted by an electric actuator (EA) and a magneto-rheological damper (MRD) in parallel connection form, under the working condition of semi-active control and energy-regeneration, it is necessary to reduce the vertical acceleration of the vehicle's body and the control energy consuming. To solve the problem of control performance evaluation of the algorithm, the concept of energy consume and control performance ratio (ECR) is put forward and theoretically analyzed based on the original evaluation indexes. Under the condition of random road surface of grade C, the influence of vehicle's velocity on the ECRs of three skyhook damping semi-active control algorithms, such as skyhook ON-OFF, constant skyhook and improved skyhook, is analyzed. The effectiveness of the ECR for evaluating the performances of the three control algorithms is verified from the viewpoint of time domain. And the optimal skyhook control algorithm is obtained. The result indicates that the improvement effects of the skyhook ON-OFF, the constant skyhook and the improved skyhook semi-active control algorithms on the performance of ride comfort increase successively, the ECR can evaluate the performance of the three control algorithms effectively, and the constant skyhook algorithm has the best comprehensive control performance and is suitable for the self-power supply of CES.关键词
