The dynamic matrix control is a wildly-used kind of predictive control calculation

which has been applied to industry control more and more because it is simple to build mold and easy to use online. Hydroelectric regulating system is a non-liner

change able parameter

non-minimum phase system

the satisfied control result can no be attained using the traditional control means. This paper applies the dynamic matrix control calculating way to regulate the hydroelectric system

the imitating result shows that it controls rotating speed of hydroelectric set rapidly and steadily.
