Abstract
In a technique of monitoring whether a physical system is normal or abnormal by continuously comparing a phenomenon taking place in the system and a phenomenon taking place in a model and also in a technique of control adopting evaluation functions using an error quantity in the model, the phenomena in both the physical system and model can be optimized. An equivalent electric circuit to the physical system is produced, and an input is provided to both of the system and the circuit. In this state, the output of the physical system and the reference value of the equivalent electric circuit are compared. The use of the equivalent electric circuit permits solving the problem inherent in the prior art that the time necessary for analog-to-digital conversion and numerical calculations is longer than the time of the actual phenomenon and disables real time simulation.
