Intelligent Control of Dynamic Performance of Vehicle Electric Power Steering and Active Suspension Integrated System

Abstract

Abstract: Aiming at complexity, uncertainty and non-linearity of electric power steering and active suspension integrated system, the grey prediction fuzzy neural network control strategy of dynamic performance of integrated system is proposed based on the grey prediction theory, fuzzy control theory and neural network control theory. The dynamic response of integrated system is studied. The integrated system controller with chip microprocessor LPC2138 as kernel is designed. Based on the simulation, the real vehicle road test is done. The results show that the grey prediction fuzzy neural network control strategy can carry out real time coordinated control of the integrated system of electric power steering and active suspension, the contradiction between the ride comfort and the handling stability is alleviated and the comprehensive performance is improved.
