With threats becoming more sophisticated, improvements at the sensor and subsystem level may not be enough for missile interceptors. In this chapter, a single-loop integrated guidance and control (G&C) intercept strategy is introduced that establishes a direct link between the sensor feedback and the fin actuators. By only requiring the normal relative velocity for feedback, target acceleration limits, and the interceptor’s input–output relative degree controller design is simple. Robustness is also evident from the black-box treatment of the interceptor. The single-loop structure reduces system complexity by requiring less feedback sensors. This enables operation in sensor-denied areas and improves vehicle maneuverability from the weight reduction. An added benefit is its ability to avoid instability from spectral separation between the guidance and autopilot subsystem control loops. These capabilities stem from the high-order sliding-mode controller. Simulations compare it to a baseline G&C system, and then its practical implementation is tested through unmodeled actuator dynamics of various speeds.
