Research Institution
A recently developed nonlinear controller called theta-D and the Higher Order Sliding Mode (HOSM) control are the centerpiece around which an Integrated Guidance and Control (IGC) scheme and a nonlinear filter technique are built to enhance the lethality of hit-to-kill interceptors and offer a means to increase the maneuver ratio advantage. This proposal includes the development of a 6DOF based IGC scheme that combines the guidance and control objectives into a single framework. Nonlinear filters utilizing theta-D and HOSM are proposed in order to improve the accuracy of the target maneuver estimates. Furthermore, a novel filter based on cost function formulation and a guidance law designed to enhance system observability are to be incorporated into the IGC architecture, and various spiraling and weaving target scenarios will be used to evaluate the proposed algorithms. The outcome of this research is expected to produce sound IGC designs, based on two theoretically rigorous techniques, that substantially decrease miss distance in hit-to-kill interceptors.
