Generalized Analysis of Biased Proportional Navigation Guidance with Fractional Power Error Feedback

This study presents a comprehensive analysis of biased proportional navigation guidance laws with variable gain in the bias command that achieve stationary target interception desired impact angle under restriction permissible look angle. More specifically, this investigates shaping approach, which takes function given by product factors range and The linear feedback fractional power impact-angle error are considered for structures. For each form, examines conditions should be satisfied functions to guarantee mission accomplishment without violation constraints. particularly focuses on estimating set feasible initial or final ensure compliance constraints along trajectory. Numerical simulation is performed flight-path angles verify analytical results. findings provide general foundation design nonswitching law control limited through profiles.
