Optimality-Based Trajectory Shaping Guidance Design

Abstract

A design and implementation scheme for the trajectory shaping guidance is discussed in this paper. The guidance law is assumed to be in some feedback form with unknown gains. The gains are then parameterized and obtained by solving a finite-dimensional parameter optimization problem. The advantage of this approach is that the control law would be in a feedback form while maintaining optimality. Furthermore, the design parameters are exactly the guidance parameters for implementing a guidance law.
