基于模糊控制的两级串联式ISD半主动悬架

he inerter-spring-damper (ISD) system is called for short ISD suspension system. In such a suspension system, the first stage is a conventional passive suspension, and the second stage is a parallel inerter-spring-damper. The two-degree of freedom suspension model was built up and a two-input one-output fuzzy controller was designed. And taking the filtered white noise as random road input signal the simulation studies of semi-active suspension model with the software of Matlab/Simulink was carried out. The simulation results show that compared with the ISD passive suspension, the two-stage series-connected ISD semi-active suspension system with the fuzzy controller greatly reduces the vertical acceleration and tire dynamic load so that improves the ride comfort and safe performance.
