| Abstract: | With regard to nonminimum phase characteristics of the aircraft in automatic landing,a stable inversion-based longitudinal automatic landing control law is designed.By solving the bounded solution to system internal dynamics,stable inversion for the desired output trajectory is designed.Based on the relative degrees of the aircraft plant,a smooth and continuous desired landing trajectory is devised as well.The stable inversion controller is used to produce the desired control input and state trajectory whil... |
