Hybrid Fuzzy-PID Control of a Semi-Active Quarter Car System
In this paper, performance evaluation of nonlinear quarter car model having three degrees of freedom is considered for uncontrolled and fully controlled suspension system in terms of passenger ride comfort
issues.Magneto-rheological (MR) damper in combination with Hybrid Fuzzy- PID controller (HFPID) is used in primary and secondary suspension system of semi-active vehicle for vibration control purpose. Simulation results for uncontrolled and fully controlled cases are calculated in time domain while the vehicle travels over the sinusoidal roadprofile. The calculated simulation results show that the proposed semi-active quarter car model provides better performance in achieving desired ride comfort and safety of traveling passengers compared to uncontrolled one.
