Abstract

This study investigates the use of pneumatically actuated active suspension system to improve ride performance of the vehicle. The mam content of this study is the development and application of the Knowledge-Based Fuzzy (KBF) multiple Proportional-Integral (PI) control scheme and the investigation of the force tracking control system that can provide improvement in vehicle ride performance. These two controllers are arranged in a separated control loops called the inner loop controller for force tracking control of the pneumatic actuator and the outer loop controller using KBF multiple PI control to reject the effects of road-induced disturbances. The performance of the proposed controller is compared to the multiple PI controller without KBF scheme and the existing passive suspension system. Simulation studies are presented in time domain simulation while the experimental evaluation is conducted on a full-scale quarter car test rig. In general, it can be reported that the proposed control scheme is able to provide improvement in terms of body states compared to its counterparts. The proposed scheme is also easy to realize in practice due to its simple structure.
