横向互联空气悬架车身高度调节模糊控制
Fuzzy Control of Body Height Adjustment for Vehicles with Laterally Interconnected Air Suspension System
摘要
Abstract
In order to overcome the defect or difficulty of making full use of height adjustment due to structure characteristics of laterally interconnected air suspension,body height adjustment strategy specific for laterally interconnected air suspension was established.To solve the problem of overshoot caused by the nonlinearity and time lag of air suspension system during height adjustment,fuzzy height controllers were designed.Two two-dimensional fuzzy controllers were applied respectively to control the front and rear air springs:the input of the front controller was determined by target height which can improve the precision of adjustment,while the input of rear controller was determined by the actual body height in front air spring,thereby enhancing the stable performance problem of body posture during height adjusting.The results show that the front controller is in collaboration with the rear controller.Also,the problem of overshoot is alleviated and the body posture keeps stable.关键词
