The CO-Simulation Research of Vehicle Active Suspension Based on Fuzzy Control

Abstract

Based on the vehicle dynamics theory, the 2-DOF active suspension model was studied to establish its dynamic model and the road model. Besides, the fuzzy controller were designed with dynamic deflection of the suspension as the controlling object. The 2-DOF active suspension model was established in Adams/View and the stochastic uneven road model was established in Matlab/Simulink in combination of the fuzzy controller to joint CO-Simulation analysis . The results show that the active suspension can effectively suppress vehicle vibration, and improve the riding performance and security.

Based on Single Neuron PID Control of Vehicle Active Suspension System

“…Active suspension. In order to overcome the shortcomings of the passive suspension, Fedrspiel Labrosse, Professor of active suspension design in institutions increased by an actuator, and rely on outside supply of energy, the initiative by the actuator force, active inhibition of body the movement of the suspension is always in the state of the optimal damping [3]. Its structure is shown in Figure 2.…”
