In order to improve the issues in designing fuzzy logic controllers, an intelligent control method using vector decoupled clouds model is proposed. The transformation between qualitative and quantitative knowledge is presented via qualitative control mechanism of clouds model to guarantee the transfer of linguistics’ uncertainty. With the vector decoupled control, the multi input variable of high order non linear system can be consolidated to single one. Meanwhile, the rules of clouds model controller are predigested and the stability of the closed loop is guaranteed. Finally, the vector decoupled clouds model controller is used to control ball and beam system, and the simulation results demonstrate the effectiveness of the method.
