Abstract
A process control apparatus capable of adjusting control constants of a process control operation which controls a controlled process. The process control apparatus includes an identification signal generator for producing a maximum length sequence signal, an adder for adding this maximum length sequence signal and a control signal and supplying it as an operation signal to a process, an operation circuit for identifying the pulse transfer function of a process response from the process signal and the operation signal and processing the transfer function by Laplace-transforming the step response of the pulse transfer function, and a circuit for processing control constants according to the transfer function.
