Abstract:

A concept of system effective matrix is presented, and subsequently, a new method-effective matrix based diagnosis is given. The kernel of this method consists in system measuring equations and system effective equation. The former describes the behavior and output (measuring) of the system. The latter describes the effectiveness of the system components. The signal analysis and process can be conveniently combined with the faults location by this method.
