Design of1PID Controller9using ABC9for9Full Vehicle Nonlinear Active Suspension System with Passenger Seat

Abstract

This paper present a modeling and control of the nonlinear full vehicle active suspension system with passenger seat utilizing PID with artificial bee colony (ABC) algorithm technique. Five PID controllers are used . The main objective of designing the controller is to improve the performance of suspension system , while the aim of suspension system in automobiles is to isolate the road disturbance experienced by the tires from being transmitted to the passengers. The effects of the nonlinear forces which come from damper, spring , actuator and parametric uncertainty in the spring, damper and actuator has been considered, therefore robust control is utilized. The MATLAB environment is utilized to determine the performance of the proposed control scheme. A comparison is performed to illustrate the effectiveness of PID-ABC controller in terms of modifying the ride comfort and the safety of travelling passengers.
