摘要： A digital PID process control apparatus is proposed wherein dynamic characteristics of the process are identified by supplying a persistently exciting signal to a closed-loop control system, and the persistently exciting signal is not supplied to the system after identification is completed, thereby tuning PID control parameters in accordance with the identified pulse transfer function. The control apparatus has a detector for detecting model error of the process in operation, a pulse generator for superposing a pulse signal on a set-point signal to the process when the model error is detected, a calculator for detecting a transient change in the model error when the input signal to the process changes in a pulse form, and a restart circuit for restarting generation of the persistently exciting signal when a change in the model error is detected, and for restarting an identification/tuning function.

摘要： A process control apparatus is provided which has a PID controller to which is supplied a sampled signal of a control deviation signal of a process value signal and a reference signal and which generates a PID control signal according to sampled-value PID control constants. A non-linear controller is connected in parallel with the PID controller. A sum signal of the output signals from the PID controller and the non-linear controller is supplied to a process through a holding circuit. The process control apparatus further includes a circuit for identifying the dynamic characteristic of the process according to the sum signal and the sampled signal of the process value, and a circuit for calculating a transfer function of the process in the Laplace operator domain and for determining the sampled-value PID constants of the PID controller according to the dynamic characteristic.

摘要： A process control system in a multi-input/output coordinate control system for executing coordinate control of a main input. The process control system sets an operating point set value for an operating point of an n-th control output, generates the n-th control output to control the main input based on the n-th control output, and generates 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.
