Process control system

A process control system in a multi-input/output coordinate control system for executing coordinate control of a main input. The process control system includes operating point setting means for setting an operating point set value for an operating point of an n-th control output, n-th output control means for generating the n-th control output to control the main input based on the n-th control output, and m-th output control means for generating an m-th control output to control the operating point of the n-th control output so that the operating point of the n-th control output becomes equal to the operating point set value, thereby to allow the n-th control output of fast response to operate at the operating point set value by controlling the main input.
