Abstract : This article concerns a nonlinear kinematics model of space interception. Nonlinear optimal control is sought through use of inverse systematic methods. A theoretical nonlinear terminal guidance law of global state feedback is advanced. In addition, a simulation test is carried out and a comparison is made with proportional guidance. Results show that this guidance law performs satisfactorily.
