Experimental investigation of active suspension force control of electric motor driven actuator with estimation and tracking control strategy

Abstract

Owing to the fastest developments of automotive electronics and control, a considerable focus is being provided on application of such techniques in automotive suspension applications. This paper presents an active force control of suspension system with Electrical actuator. To supress the variation of the sprung mass, the Mamdani fuzzy logic is used. Moreover, the unknown disturbances are compensated by active force control loop. The fuzzy logic based disturbances compensation was performed by active force control loop (AFC). The effectiveness of Fuzzy controller and AFC loop controlled electrical actuator active suspension system was validated through numerical simulation and Rapid control prototyping experiment testing under the ISO-8608 suggested road surface. The quarter car model-electric actuator active control scheme was implemented to suppress the vibration of suspension system. The outcomes of the assessments exhibit that the recommended suspension can easily adopt its control scheme to attain a better enhancement than that obtained by conventional suspensions.
