Fuzzy-PID切换控制在磁流变半主动悬置系统中的应用
Applying Fuzzy-PID Switching Control to Magnetorheological Semi-active Suspension System
摘要
Abstract
The dynamic model of a new type of powertrain magnetorheological (MR) suspension system was built and experiments on its dynamic characteristics were carried out.The numerical fitting method that establishes the relationship between the current and the controllable damping force is applied as a theoretical model to control the MR suspension system.With the equivalent stiffness and equivalent damping of the powertrain MR suspension system considered,the model of MR semi-active suspension system was constructed.The fuzzy-PID switching control strategy was designed for the MR semi-active suspension system.Then its vibration isolation performance was simulated under different working conditions.The simulation results show that the MR semi-active suspension system has good effects on vibration isolation with the use of the fuzzy-PID switching control strategy.关键词
