Abstract

Vibration control of a Quarter car model is one of the important factor to improve the travel comfort of the passenger. Many researchers developed control strategies for 2 Degree Of Freedom (DOF) quarter car model. In this paper, travel comfort of the passenger is analyzed by designing and simulating the Fuzzy Logic Controller (FLC), Sliding Mode Controller (SMC) and Fuzzy SMC (FSMC) for an 8 DOF quarter car with integrated Seat suspension and Driver model. While testing the performance of the controllers, the system is subjected to four types of road disturbance individually. The responses are compared with each other along with the passive system. The results show that FSMC reduced the Vibration (89.97%) than the FLC, SMC and passive system.
