Research on nonlinear systems is of great worth, and has certain guiding significance in design and application of control systems. In the paper, the state feedback predictive control theory is applied for a class of affine nonlinear systems. The optimal control law and the expression of algorithm of the system are obtained. Stability analysis of nonlinear systems is researched. Simultaneously, the validity of algorithm is proved by simulation. It attests that the state feedback predictive control improves the stability of the system.
