Abstract:

It is difficult to establish the precise mathematical model of fermentation temperature，for the complex reaction mechanism of the beer fermentation process.Fermentation temperature plant is a large time-delay system，some typical algorithms for this kind of systems can not act a good effort as the precise model for this process can not be got.It will be more difficult to guarantee the effort of the controller while the interference in the fermentation process is unpredictable.Aiming at these problems，a new predictive control strategy which can quickly suppress disturbances has been provided by this paper.The strategy is based on the idea of single step control of dynamic matrix control（DMC），and combines the advantages of both time optimal control and DMC.It is proved by the simulation result that this strategy acts a good effect on the fermentation temperature control and will quickly suppress the interference.
