A multivariable unified predictive control (UPC) algorithm based on the state-space model

As a kind of predictive control method, advantages of the unified predictive control (UPC) have been demonstrated in several publications. With UPC, different controllers can be designed under a unified frame, which overcomes the difficulty of comparing control results when the controllers are designed in general way, and the cost of design is reduced considerably. However, UPC also has its drawback. When it is applied to solve the problem of multivariable control, the algorithm is too complicated, therefore, there are many difficulties for it to be implemented and analyzed. A new kind of algorithm based on the state-space model is presented in this paper. The limitation of the original algorithm is overcome. It is an extension of the unified predictive control. Simulation results are given.
