Abstract:
|
A novel algorithm for making the combination of outputs in the output zero direction of
the plant always equal to zero was formulated . Using this algorithm and the result of
MacFarlane and Karcanias , a fault detection scheme was proposed which utilizes the
directional property of the multivariable linear system . The fault detection scheme is
applicable to linear multivariable systems . Results were obtained for both continuous and
discrete linear multivariable systems . A quadruple tank system was used to illustrate the
results . The results were further verified by the steady state analysis of the plant . |
