Abstract: Based on kinetic analysis,a unified method for mobile manipulator is proposed to establish an integrated kinetic model.Aiming at its nonlinearity,this model is transformed into T-S(Takagi-Sugeno) fuzzy model.After that,a state feedback controller based on Linear Matrix Inequalities(LMI) is designed and the stability of the system is proved.The efficiency of the method received supports from the simulation results.
