And then,corresponding to the linear state equation,by solving a Linear Quadratic Regulator(LQR) problem,the robust optimal control law is obtained,which guarantee that the joint variables converge into the given point asymptotically in global sense.

But because of the model's uncertainty of parameters and its liability to be affected by external non-linear disturbances,linear quadratic optimized control has been adopted,paired .
