摘要：To approach an effective vibration control, the emphasis of the research is an adaptive control method for vehicle suspension system. Because of the features of the passive suspension's structure, the system can only store or exhaust the body vibration energy. So the conception of active and semi-active suspension has been advanced, which give a new way to improve the vibration performance of suspension system. The Least Means Squares (LMS) adaptive filtering algorithm is used in active suspension system. With adjusting the weight of the adaptive filter, the minimum quadratic performance index is obtained. For the vibration control of two-DOF vehicle suspension model, the simulation results show that the body's vertical vibration control based on the adaptive filtering algorithm is prominent under the excitation of road signal.
