INTELLIGENT FAULT-TOLERANT CONTROL OF MR SEMI-ACTIVE CONTROL FOR A HIGHWAY BRIDGE

摘要：

An intelligent fault-tolerant control (FTC) strategy is investigated for MR semi-active control system with sensor failure. Based on the adaptive neuro fuzzy inference system (ANFIS),sensor failure can be on-line detected and switching control strategy of determining the commanded voltage for MR dampers is proposed. When sensor is healthy,voltage determined by fuzzy logic control (FLC) will be applied to the corresponding MR damper. On the other hand,if sensor has failed and been detected using ANFIS,switch is activated and passive-on voltage will be applied to MR damper. Benchmark control problem for a seismically excited highway bridge using FTC is simulated,results demonstrate the effectiveness of the proposed method,and some useful conclusions are also obtained.
