The Application Of Predictive Control In The Non-minimum Phase System

In the modern scientific and technological development process, the predictive control theory, applied more widely, it has become the field of industrial control an indispensable tool for researchers are increasingly subject to attention.This paper first analyzes the non-minimum phase system, and then several of the predictive control algorithm 11 was introduced, the last for a class of typical non-minimum phase systems - turbine-conditioning systems, because of right-half plane zero, and often the accused object appears negative transfer phenomenon, the use of traditional linear control techniques is difficult to eliminate this feature. Give full play to the advantages of predictive control algorithm to improve the non-minimum phase system control quality, which is to be discussed in this paper the main content, but also the essence of predictive control theory. After matlab simulation results show that the predictive control of dynamic matrix control algorithm and generalized predictive control algorithm can be well applied to control hydraulic turbine regulating system, and has a good robustness.
