Abstract

Purpose

The purpose of this paper is to propose a novel design for determining the optimal hybrid fuzzy PID-controller of an active automobile suspension system, employing the gravitational search algorithm (GSA).

Design/methodology/approach

The hybrid fuzzy PID-controller structure is an improvement to fuzzy PID-controller by incorporating a fast learning PID-controller.

Findings

The GSA can adjust the parameters of the PID-controller to achieve the optimal performance.

Research limitations/implications

The GSA may have the advantage of quick convergence, but the required computation may be intensive.

Practical implications

The simulation results demonstrate the effectiveness of the proposed approach on active automobile suspension system.

Originality/value

In order to demonstrate the theoretical guarantee of the proposed method, comparisons with particle swarm optimization or other methods has also been carried out.
