Generalized model predictive static programming (G-MPSP) technique was presented in this paper in continuous time framework for rapidly solving a class of nonlinear optimal control problems with hard multiple terminal constraints. A key feature of the technique is backward propagation of a small-dimensional weight matrix dynamics, using which the control history got updated. It leads to a static optimization problem and it is the reason for its high computational efficiency. Different maneuvering ground targets were considered in the simulation studies. Simulation results show that final miss distance is less than 1.0 m, terminal impact angle errors are less than 0.1°. Impact angle constraints are met in addition to achieving near zero miss distance and the variation in the lateral acceleration history is quite smooth throughout the engagement.
