This study develops an augmented-zero-effort-miss/zero-effort-velocity (A-ZEM/ZEV) guidance algorithm, which integrates an adaptive collision avoidance module designed to maintain obstacle clearance while optimizing fuel consumption. The A-ZEM/ZEV guidance algorithm predefines parameters for step-shaped obstacles to ensure avoidance within a specified risk altitude band and dynamically adjusts parameters for glide-slope obstacles to meet varying slope requirements. Through rigorous simulation testing, the robustness and reliability of the A-ZEM/ZEV guidance algorithm are demonstrated. Further, an in-depth analysis of parameter sensitivity has been conducted, revealing that the fuel efficiency of the A-ZEM/ZEV guidance algorithm is on par with the classical ZEM/ZEV methodology. The contributions include the introduction of a height constraint adaptation mechanism for different step-shaped obstacle lengths and minimum safe heights, and the embedding of velocity information in the performance index for glide-slope collision avoidance, providing a viable solution for complex landing scenarios.
