Abstract
A process control apparatus wherein dynamic characteristics of a process are identified in accordance with process inputs and outputs, so as to tune digital PID (Proportional-Integral-Derivative) parameters in accordance with the identified dynamic characteristics. The process is an N-input/output process having an interference between the process inputs and outputs. Each transfer function between a given process input and process output is identified. A transfer function between a set-point signal and the process output is obtained and matched with that of an N-input/output decoupled reference model, to tune the PID parameters.
