Abstract

Nowadays, there are many methods for synthesizing structure and parameters for controllers in control systems with industrial objects. But the methods often focus computation for single-stage control systems, while industrial control systems are often multi-stage systems. One of the big problems that the control system calibration engineer in the industry often encounters is the uncertainty of the object, it causes the system parameters to change, leading to the quality change according to the trend bad after a period of operation, it is necessary to re-adjust that parameter, so that the system works with the required quality. Therefore, this paper presents a general method to calculate the control system for the uncertain industrial object.
