The purpose of the present study is to address the half-vehicle nonlinear suspension control using PSO-based fuzzy gain scheduling of PID controllers so that the gains of PID controllers can be scheduled in the course of operation through the application of an intelligent FLC while the fuzzy rules are optimized in the search space of error and derivate of error via a metaheuristic population-based PSO algorithm.

That is why, in such a case we propose to synthesize the model control loop with an adaptive, gain scheduling controller and a nonlinear model of the process.
