Development of an Aircraft Auto-landing Guidance System using Time Delay Control, and Simulation with Crosswind and Aileron Fault

Abstract

A design procedure for aircraft auto-landing guidance using time delay control (TDC) is proposed, and the designed guidance system is validated via simulations of general landing procedures, including glide slope, flare and touchdown. The simulations adopt a nonlinear dynamics model that includes the landing gear. Additionally, by employing TDC, a stability and control augmentation system, a longitudinal auto-landing guidance law, and a lateral guidance law considering crosswind are proposed. The designed auto-landing guidance laws are evaluated through simulations with aileron fault and crosswind disturbance. The proposed TDC-based auto-landing guidance law shows good performance and is robust when aileron fault and crosswind are included.
