磁流变半主动悬挂引入位置阈值的改进Bang-Bang控制
Improved Bang-Bang Control of a Magneto-rheological Semi-active Suspension Introducing Position Threshold
摘要
Abstract
To improve the ride comfort of vehicles, the problem of overlarge passing-through velocity across the balance location in the Bang-Bang control algorithm is studied. An improved Bang-Bang control algorithm with position threshold introduced is proposed to reduce the crossing speed. Since a single performance index is difficult to realize comprehensive evaluation of suspension performance, a weighted comprehensive evaluation index considering the weight of each index is built. Based on a magneto-rheological semi-active suspension, the principle and value acquisition of the simple Bang-Bang control algorithm and the improved Bang-Bang control algorithm are analyzed. And their performances of vibration control are simulated and tested. The results indicate that the comprehensive evaluation index can effectively realize the comprehensive evaluation of suspension performance; the improved Bang-Bang control algorithm can effectively decrease the passing-through velocity of the vehicle’s body across the balance location, reduce the vertical acceleration of the vehicle’s body, and then improve the ride comfort.关键词
