Abstract:

In this paper, an active suspension system, combined with classical leaf springs and shock absorbers, is developed by use of a vehicle plane model without feedback filters in control system. A method of stochastic parameters optimization has been utilized in order to optimize PI controller parameters. The basic optimization goal was a simultaneous minimization of sprung mass acceleration and standard deviation of forces in tire-to-ground contact area, so as to improve vehicle comfort and handling performances.
