Abstract:

GUIDANCE LAWS THAT OPTIMALLY UTILIZE THE ENERGY AVAILABLE FROM DISTURBANCES TO AID THE GUIDANCE MAY MINIMIZE THE WEIGHT AND VOLUME OF THE GUIDANCE SYSTEM WHILE PROVIDING ACCURATE TERMINAL HOMING. CLASSICAL GUIDANCE LAWS, INCLUDING PROPORTIONAL NAVIGATION GUIDANCE (PNG) PROVIDE ACCURACY BUT DO NOT MINIMIZE OR UTILIZE DISTURBANCE EFFECTS. MODERN TECHNIQUES SUCH AS LINEAR-QUADRATIC-GAUSSIAN OPTIMAL CONTROL TREAT DISTURBANCES AS NOISE. THIS DOES NOT PROPERLY ACCOUNT FOR WAVEFORM DISTURBANCES, SUCH AS WIND, OFTEN RESULTING IN DEGRADED PERFORMANCE DURING REALISTIC DISTURBANCES. SPARTA PROPOSES TO STUDY TWO GUIDANCE TECHNIQUES, INTEGRAL GUIDANCE (IG), AND NOISY DISCRETE DISTURBANCE UTILIZING CONTROL (NDDUC), WHICH HAVE, IN PAST APPLICATIONS, PROVIDED EXCELLENT ACCURACY IN TERMINAL HOMING MISSILES WITH REALISTIC DISTURBANCES. IG IS SIMILAR TO PNG EXCEPT THAT A LINE-OFSIGHT ANGLE TERM IS ADDED TO THE GUIDANCE LAW WHICH MINIMIZES THE EFFECTS OF DISTURBANCES. NDDUC IS AN IMPROVEMENT OVE LQG METHODS IN THAT WAVEFORM DISTURBANCES ARE CONSIDERED IN FORMULATION OF GUIDANCE LAWS AND PROCEDURES ARE STRUCTURED SO THAT FORCES CAUSED BY DISTURBANCES ARE OPTIMALLY UTILIZED IN PROVIDING CONTROL FORCES, THUS MINIMIZING THE ENERGY REQUIRED FOR GUIDANCE.
