Abstract

Passenger travel comfort is important while analyzing the vibration control of a quarter car model. To achieve the same, various control strategies are employed by the researchers for a 2 Degree of freedom (DOF) quarter car model. We analyzed travel comfort of the passenger by designing and simulating the PID controller and Fuzzy logic controller (FLC) for an 8 DOF quarter car with integrated seat suspension and driver model. While testing the performance of the controllers, the system was subjected to four types of road disturbance individually. The responses were compared with each other along with the passive system. The results show that FLC increases the ride quality better than the PID and passive system.
