Controllability of uncertain polynomial fuzzy singular systems

This paper considers I-controllability, R-controllability and C-controllability of uncertain nonlinear singular systems. The polynomial fuzzy model is constructed for uncertain to eliminate the upper and lower bounds restriction of states in the system and reduce the calculation quantity. Sufficient conditions, based on a polynomial fuzzy model, are proposed to guarantee the controllability of the system. Finally, an example is performed to verify the merits of the method proposed.
