ABSTRACT:
A self-propagating control apparatus includes a propagating-type controller, which has a proportional integration element and a plurality of phase compensation elements, and a supervisor for judging the status of a controlled system and delivering commands to the propagating-type controller. The apparatus is characterized in that operation starts out from a PID action, which is based on experience accumulated at the site, and the propagating-type controller is caused to propagate or self-enhance under the supervision of the supervisor to gradually improve capability. The apparatus exploits on-site experience and is capable of exceeding limitations PID control without requiring a high level of expertise for design and readjustment.
