Adaptive Cascade Generalized Predictive Control

General block diagram of cascade control

Cascade control is one of the most popular structures for process control as it is a special architecture for dealing with disturbances. However, the drawbacks of cascade control are obvious that primary controller and secondary controller should be tuned together, which influences each other. In this paper, a new Adaptive Cascade Generalized Predictive Controller (ACGPC) is introduced. ACGPC is a method issued from GPC and the inner and outer controllers of a cascade system are replaced by one cascade generalized predictive controller, where both loops model are updated by Recursive Least Squares method. Compared with existing methods, the new method is simpler and yet more effective. It can be directly integrated into commercially available industrial auto-tuning systems. Some examples are given to illustrate the effectiveness and robustness of the proposed method.

Structural characteristics of Mulato Grass under different cutting Heights

Bookmark and Share

Author: Eneas Reis Leite

Native pastures are the main sources of food for ruminants in Northeast Brazil. Considering that animal feeding represents 70% to 80% of total costs, it is justifiable to maximize the use of pastures. Their correct use allows the conversion of structural carbohydrates into proteins of high biological value at a relatively low cost.

Grasses from Brachiaria genus are the basis of animal production in the tropics, allowing extensive areas for livestock Continue reading
