<p>PURPOSE:To diagnose and adjust a control characteristic of an automatic control system by an optimum control constant, by performing it by deriving a frequency response characteristic and a step response characteristic, in case when a simple adjustment is enough, and performing it by deriving a Bode diagram, etc., when a precise adjustment is required. CONSTITUTION:When a simple adjustment is enough, a frequency response characteristic and a step response characteristic are derived by a transfer function measuring device 21, and in case when those are unstable, stable frequency response characteristic and step response characteristic are obtained by executing experientially a trial-and-error and adjusting a loop gain of an automatic control device 10. On the other hand, when a precise adjustment is required, a Bode diagram is prepared by a simulating circuit 30, an optimum control constant is calculated, based on this Bode diagram, and a control characteristic of the automatic control device 10 is adjusted by this optimum control constant. In this way, the control characteristic can be standardized and converted to a high accuracy.</p> |
