Wild Goat Optimization-Based Robust Controller for a Vehicle Suspension System

This research introduces a PID controller designed for a Vehicle Suspension System (VSS) using the Wild Goat Optimization (WGO) algorithm. The goal is to improve ride comfort by mitigating the impacts caused by uneven and rough roads. The VSS model utilized for designing the WGO-PIDC is a fourth-order system. By integrating the WGO algorithm, the conventional PID controller is enhanced to achieve better control performance. The superior control performance of the WGO-PIDC is confirmed through a comparative analysis with other well-known control methods. The comparative outcomes indicate that the proposed approach is highly effective for maintaining dynamics of the VSF within a steady range, thereby ensuring precision, stability and robustness.
