Abstract

This paper presents a structured fuzzy system for fault diagnostics in a brake-by-wire system. Our focus is on the power electronics switches within an electrical motor. We have developed a simulated model of brake-by-wire system to generate current and voltage signals under the normal condition and six faulty conditions in the power electronics circuit. Our experiments show that the proposed fuzzy diagnostic system is effective in accurately predicting faults as well as the location of faults.
