- Abstract
- In this work first a linear observer-based method is applied to detect faults in a continuous stirred tank reactor (CSTR) and it is demonstrated to provide acceptable performance in spite of its practical restrictions. This is for the most part as a result of the fast and relatively detectable response of residuals to the occurrence of fault, and practical restrictions are due to the constraints imposed on the range of initial conditions in which the system should rest before the start of fault detection. As a second approach, the intrinsically nonlinear method of particle filters is applied to detect the same fault as in the first method. Making use of simulations, a thorough comparison between these two techniques is extracted in terms of some significant aspects of a desirable fault diagnosis system. The result of the comparison renders beneficial information about the advantages and drawbacks of the applied methods and makes it easier to decide which method to apply on practical systems in various situations.
