PURPOSE:To establish the monitoring index with quantitative stability, by calculating the monitor index with the output of the memory unit provided for the unit solving the equation of the system having feedback. CONSTITUTION:In monitoring the stability of the system having feedback, the control variable x is fed to the integrator 1 and the monitored amount y is added to the integrator 1', and the signal from them is directly fed to the memory unit 5 via the integrator 2 and the switch unit 4. Switch is turned on in the unit 4 only when the signal from the unit 3 generating a signal every given time is received, and the unit 5 moves the new memory to the old address of memory stored when the signal is received and the input from the unit 4 is stored to the vacant address. Further, the output of the unit 5 is given to the unit 6 which solves the equation of the system having feedback to compute the equation 1 in which t is time and a, b are constants, allowing to output the monitoring index from the unit 8. Thus, the monitoring index having quantitative stability can be obtained. |
