Interdependent Estimation and Guidance with Zero-Effort-Miss Enforcement

An interdependent estimation and guidance design approach for interceptors is presented by enforcing a stable zero-effort-miss dynamics. The output of the estimator is the demanded lateral acceleration, which serves as the guidance command. A dynamic inversion based inner-loop autopilot design facilitates extensive six degree-of-freedom simulation studies, which shows that the proposed interdependent approach gives improved performance compared to the conventional approach where estimation and guidance are done separately.
