Intelligent Control System for Automotive Suspension Based on Magneto-rheological technology
The research on intelligent control system for automotive suspension in Chongqing University involves the actuator,sensing and control technology.The actuator technology involves the panorama of fundamental design theory and design modes,sealing technical study and accumulator compensation,magnetorhelogical(MR)damper manufacturing,testing and modeling,durability test and dynamic response analysis,etc.MR semi-active control research of suspensions involves the vehicle dynamics modeling,control strategy development,control electronics implementation,road test and appraisal.Based on the vehicles investigated,specific dynamics model is built to simulate the ride comfort and steering stability.Sky-hook control,fuzzy control etc.have been realized in specific object,and initiated wavelet frequency domain control strategy,the comparison of control effect under different controls is performed.A human simulated intelligent control(HSIC)scheme is formulated and implemented to attenuate unwanted vibrations such as pitch angle acceleration.Electronics implementation is based on the DSP technology,which is suitable for the digital signal processing.After the integration onto vehicles of the MR damper and control electronics,the experiment is carried out on a mini-bus and a passenger car respectively.The results show that good vibration suppression effect is achieved,especially in rough roads,simultaneously,the steering stability is improved.
