Abstract: Effective partition of the input and output spaces must be involved when sample data is transformed into some qualitative rules.When dealing with multidimensional sample data，the point mentioned above is much more difficult.For the purpose of handling that problem，an improvement on scale cloud transform method is proposed，named two-dimension scale cloud transform method with the purpose of handling two-dimension sample data.The two-dimension T-S cloud controller also presented.An example is researched to prove the validity of this new method，and the simulation results show that the new method is simple，powerful，and the new T-S cloud controller consisted of the rules generated by the new method can reproduce the original data very well，and that the number of intelligible rules is few.
