１制御異常診断装置。The input signal to the plant analog control device and the output signal of the device are connected to an isolation amplifier and A-D, respectively.
The data is input to a digital computer via a converter and compared with the output value using a mathematical model of the plant control system stored in the computer to detect abnormalities in the plant analog control device and displayed on the display. In this system, a changeover switch and a constant voltage power supply, which are switched by the plant control system mathematical model output, are installed at the input terminal of the isolation amplifier.
In addition, a failure detection algorithm for the abnormality diagnosis device is provided inside the digital computer, and a NOT circuit for inputting the output of the failure detection algorithm and an AND circuit for inputting the output of the NOT circuit and the output of the plant control system formula model are provided at the output terminal of the digital computer. A Plan 1 control abnormality diagnostic device characterized by:
