英文摘要: The project is devoted to improving the tracking capability and flight performance of Unmanned Aerial Vehicles (UAV), and investigating new control methodologies suitable for underactuated UAV tracking control.In view of the aerodynamic model uncertainties, unknown external air disturbances and control constraints, this project takes the underactuated quadrotor helicopter system as a controlled plant to study the corresponding trajectory tracking and path following control design principle and method, including (1) adaptive trajectory tracking control with aerodynamic model uncertainty and unknown external air disturbance, (2) guidance integrated path following control based on Parallel-Transport frame, (3) modified Rodrigues parameter based nested saturation tracking control, (4) adaptive command filtered trajectory tracking control with magnitude and rate constraint, as well as (5) numerical simulation and real-time flight experiment of an unmanned Quadrotor helicopter. Viathework supported by this project, it will provide several effectivetraking and saturation control design methodolies for the unmanned quadrotor helicopter, and therefore willpromote the research of the UAV flight control theory and theapplication of the nonlinear control theory in practice.
