Embodiment Construction

[0013] The present invention will be further described below in conjunction with accompanying drawing:

[0014] The present invention is made on the basis of drawing lessons from domestic and foreign advanced control technologies. Since the 1980s, the DCS system has been widely used, but the practical application is basically based on single-loop PID control. From the perspective of control performance, the functions of the computer have not been fully utilized. In order to meet the requirements of further improving the economic benefits of enterprises, many researchers have proposed advanced process control strategies and have been successfully applied. Advanced Process Control (APC) refers to a class of model-based operational and technical strategies that take full advantage of computer power to maximize profits for a plant. After the advanced control is implemented, the system can run in the best working condition to realize optimized production. At present, the advanced...

Abstract

The method is used for improving the bad robustness when a normal manufacturing process in petrochemical industry and pharmacy industry is taken as a controlled object. It comprises: 1) establishing a advanced process-controlling software frame; 2) establishing the advanced process-controlling software frame core; 3) establish a human-machine interface of the advanced process-controlling frame; 4) establishing an advanced process-controlling software simulation pack to simulate each type of the controlled object. Said control system comprises an operation station, a advanced controller, a control station and a data communication network.

Description

Technical field: [0001] The high robustness advanced control method and its control system take general industrial processes in petrochemical, pharmaceutical and other industries as the controlled objects, and belong to the field of control science and engineering. Background technique: [0002] Since the 1980s, the DCS system has been widely used, but the practical application is basically based on single-loop PID control. From the perspective of control performance, the functions of the computer have not been fully utilized. Advanced Process Control (APC) refers to a class of model-based operational and technical strategies that take full advantage of computer power to maximize profits for a plant. Many foreign control software companies and DCS manufacturers have their own advanced control and advanced control commercial software packages, and they are constantly improving and upgrading. In recent years, the number of domestic APC software applications has grown rapidly a...
