Description

technical field [0001] The present invention relates to the field of predictive control, and more particularly relates to a predictive control device and method. Background technique [0002] Predictive control is an advanced computer control algorithm. It is based on a parameter model and has low requirements on the process model. It has the characteristics of softening effect, multi-step prediction, rolling optimization and online feedback correction, and has a strong ability to model structural deviations. The robustness of the control system has excellent control performance for objects with hysteresis and uncertainty, and has become one of the development directions of current process control. [0003] However, due to the large amount of calculation of the predictive control algorithm, the realization of the predictive control algorithm requires a large amount of data calculation and processing. Among the various predictive control devices (such as industrial control ma...

[0003] However, due to the large amount of calculation of the predictive control algorithm, the realization of the predictive control algorithm requires a large amount of data calculation and processing. Among the various predictive control devices (such as industrial control machines) that are currently put into use, most of them are based on von Neumann's computer-structured

Since the predictive control device based on Von Neumann's computer structure executes the instructions serially, and because the predictive control algorithm itself involves a large amount of calculation, the existing predictive control device It takes a long time to realize a predictive control operation, and the existing predictive control device can only be used for the controlled object with slow output response
