| Summary: | GBAS landing system (GLS) serves as an effective means to enhance the accuracy and efficiency of approach and landing, and it is recognized as an essential function for modern and future advanced civil aircraft onboard avionics systems. This article presents a high-precision three-dimensional GLS approach guidance algorithm. Specifically, a spatial geometric relationship-based guidance deviation calculation method and a distance correction strategy-based guidance commands generation method are developed. Subsequently, an improved active disturbance rejection control method using the sine-function is proposed to design the robust attitude controller, ensuring precise tracking of the guidance commands. Through simulations, the algorithms are verified using Monte Carlo method, and the results showcase that the proposed algorithms can provide gratifying approach and guidance capability even with wind interference, sensor noise, and model parameter uncertainties. |
