This paper developed a new microprocessor-analog mixed system to monitor I/O data of unknown plant and to identify the variation of plant parameters. To reduce calculation requirements, signal processing concerned parts are constructed by analog hardware, and the monitoring characteristics are far superior to conventional mechanical meters in their accuracy. Measuring instant values of signal is also a great advantage. Although the adaptive identification is performed by off-line algorithm because of the great amount of computation, since transition data are recorded by machine language, and then identified periodically, real variation of the parameters can be identified during operation of the plant. Case studies were performed for a known electric circuit to prove the usefulness of the system.
