Title

THE DISRUPTIVE EFFECT OF CONTROL UNITS IN FAULT DETECTION OF VEHICLE ACTIVE SUSPENSION SYSTEM WITH HYDRAULIC ACTUATOR

Pages

  443-452

Abstract

 Design of FAULT DETECTION AND DIAGNOSIS systems (FDDS), although extending the control strategies, are challenged by controller interferences in fault diagnosis. In this study, in order to improve performance and accuracy of FDDS in the fault detection process, influential parameters and the level of corresponding interferences are investigated. For this purpose, a powerful method in fault pattern recognition of industrial plants based on dynamic behavior and dynamic model using soft computing is designed and tested on simulated suspension system of a vehicle. The suspension system is one of the parts that most affects reliability and safety of the vehicle. For investigating the level of interference caused by the CONTROL UNIT, the simulations of both passive and active (equipped with hydraulic actuator) suspension systems are utilized in association with the CONTROL UNIT. The results of tests under variable circumstances (using random values) demonstrate that the presence of CONTROL UNIT restricts the FDDS process and reduces the robustness of the system against disturbances and noise. Considering the way in which the CONTROL UNIT affects the process, application of suggested solutions in this research have a considerable impact on limiting the adverse effects. Fault detection program which is provided by Matlab software is a useful tool to investigate and define the effect of CONTROL UNITs and can be considered as a useful device to facilitate the research and precipitate conduction of tests in different stages.
