Outline of Final Research Achievements

We conducted research to develop a guidance flight control system that ensures flight safety and does not burden the pilot, even when an aircraft in flight encounters a failure that renders conventional autopilot mechanisms inoperative. The study assumed the use of existing autopilots and manual pilot control in a cooperative manner, and aimed to integrate advanced control techniques such as simple adaptive control and structured H∞ control into existing flight control systems. Additionally, we investigated methods for calculating flight paths onboard that safely guide the aircraft to an airport. The validation tests were conducted not only using numerical simulations but also with flight simulators, including pilot operations, and unmanned aerial vehicles.
