Abstract

The suspension system of any vehicle is responsible for not only to support the weight of the vehicle, but also to improve ride comfort and vehicle handling by damping out the roughness of the road before transferring it to the passengers. When the vehicle experiences an uneven road profile, the suspension should not generate too large oscillations, and even if it does, then these oscillations must be removed as quickly as possible. In this paper, we have investigated the functioning of a semi-active suspension system of a vehicle by modelling it as a quarter car semi-active suspension system. The model is designed as a PID controller based semi-active suspension system. MATLAB Simulink has been used in the process. The system considered in the paper is a linear system, which can apprehend basic performance parameters of a suspension system like body and suspension travel and give results in terms of rise time, settling time and over-shoot. The performance of the system is taken as better ride quality given by body travel. The lesser body displacement (over-shoot) in earlier time (settling time) are used to depict these performance standards. These performance indicators are also compared with a passive suspension system of similar specifications. The results achieved through the simulation show that the semi - active suspension system, using the designed PID controller to adjust its damping parameters, demonstrates much better performance than the passive system, having fixed damping. The designed controller can be used to design more comfortable and stable suspension systems.
