Abstract: PURPOSE:To set the attenuation coefficient at >=1 by identifying the gain and the time constant with partial approximation of a controlled system to a primary delay system and calculating the proportion gain and the integration time by the Newton method in response to a target control response. CONSTITUTION:The gain K and the time constant T are identified by having the partial approximation of a controlled system to a primary delay system for a PI controller which gives a PI control to the controlled system having its varying characteristics.

With this method, the attenuation coefficient, i.e., an index to designate the response characteristics of the controlled system can be designated in all ranges less than and more than 1.0. Thus it is possible to comply flexibly with a request for a slow response despite the reduced overshoot for the controlled system as well as a request for a quick response despite the increased overshoot respectively.
