Design and Implementation of Fuzzy-PID Controller for an Active Quarter Car Driver Model to minimize Driver Body Acceleration

摘要

Improved driver ride quality is the sole purpose of the designed active quarter car model. In this paper an active quarter car with driver model is simulated using MATLAB/Simulink and the performance of the controllers are studied. To reduce the Driver Body Acceleration (DBA) and thus increasing the ride quality a Fuzzy Tuned PID Controller (FPID) is designed. The performance of this Controller is analyzed against the performance of Fuzzy Logic Controller (FLC), PID and Passive System for the 3 Degree of Freedom (3DOF) active quarter car driver model. The system is subjected to road disturbance such as dual bump, sinusoidal bump and random road which is designed as per ISO 8606 standards. It is proved that the FPID increases the ride quality and reduces the vibration in comparison to the FLC, PID and Passive system from the performance analysis of these controllers.
