We prove under the strong second-order sufficient condition with the sigma term that the local SQP-type method is quadrati-cally convergent and the line search SQP-type method is globally convergent.

Introduction We consider the following nonlinear semidefinite programming SDP min f x . h x 0 g x where x R f R R h R RZ and g R Sp are twice continuously differentiable functions Sp is the linear space of all p X p real symmetric matrices and Sp is the cone of all p X p symmetric positive semidefinite matrices. Fares et al. 2002 1 studied robust control problems via sequential semidefinite programming technique. They obtained the local quadratic convergence rate of the proposed SQP-type method and employed a partial augmented Lagrangian method to deal with the problems addressed there. Correa and Ramirez 2004 2 systematically studied an SQP-type method for solving nonlinear SDP problems and analyzed the convergence properties they obtained the global convergence and .
