TLDR
In this paper, an identifying operation part identifies a process parameter and a parameter operation part which obtains an optimum control parameter on a basis of the identified parameter, and a calculation result U is inputted to a plant to execute the control.Abstract:
PURPOSE:To make always a stable control of good quick responsiveness possible by providing an identifying operation part which identifies a process parameter and a parameter operation part which obtains an optimum control parameter on a basis of the identified parameter. CONSTITUTION:A process variable (x) from a process 1 is inputted to an optimum control device 4 and the optimum control operation is executed, and a calculation result U is inputted to a plant to execute the control. Meanwhile, an identifying operation part 2 of the process calculates a process parameter Pp in accordance with an identifying signal Z outputted from the process 1 to detect the variation of the process characteristic. The calculated process parameter Pp is sent to an optimum control parameter operation part 3, and an optimum control parameter Pc is operated by a prescribed operation there and is given to the optimum control device 4. Thus, the optimum control parameter which is not unstable even in the severest conditions of control and is weakened unnecessarily is obtained in accordance with the variation of the process parameter.read more
