To solve the problem of multivariable process control, a modular multivariable model algorithmic controller is introduced in this article, all the control goals are listed and achieved in refusal order. In this algorithm, modular multivariable control and model algorithmic in predictive control are combined, and stair - like control strategy is introduced as well. As a result, it＇ s possible to solve dynamic MMC problem. Using Shell problem as research object, simulation results illuminate the correctness of this algorithm, and show the characteristics of it such as simple structure, ability to solve the dynamic modular multivariable problem, less calculation time, liable to design and rebuild. Because of these characteristics, the modular multivariable model algorithmic controller has high application value.
