ANFIS based sensor fault detection for continuous stirred tank reactor
In this paper, an Adaptive Neuro-Fuzzy Inference System (ANFIS) based Sensor fault detection and isolation for Continuous Stirred Tank Reactor (CSTR) is proposed. CSTR is a highly nonlinear process exhibiting stable and unstable steady state at different operating regions. Fault detection (FD) of such a complicated CSTR process is a mind boggling problem. In this paper, an ANFIS based 'dedicated observer' scheme is dealt along with statistical methods for the detection of the fault. The result shows the feasibility of using the proposed method for the detection of sensor faults in CSTR. (C) 2010 Elsevier B.V. All rights reserved.
