This paper deals with a computational approach to the state feedback synthesis of an optimal control problem for input-affine polynomial nonlinear systems. The matrix sum of squares relaxations and semidefinite programming present feasible solutions of the state-dependent linear matrix inequality (SDLMI) based on the Hamilton-Jacobi-Isaacs inequality. A control oriented structural reduction decreases the computational amount. An additional use of a polynomial annihilator condition decreases the conservativeness of the SDLMI by ignoring the coupling condition.
