Smooth tracking control for conversionmode of a tilt-rotor aircraft with switching modeling Research Article

Kebi LUO, Shuang SHI, Cong PENG

Frontiers of Information Technology & Electronic Engineering 2023, Volume 24, Issue 11,   Pages 1591-1600 doi: 10.1631/FITEE.2300266

Abstract: This paper investigates the problem in conversion mode of a with a switching modeling method and a technique. Based on the nonlinear model of the conversion mode, a switched linear model is developed by using the Jacobian linearization method and designing the switching signal based on the mast angle. Furthermore, an scheme is designed to deal with the conversion mode control issue. Moreover, instead of limiting the amplitude of control inputs, a method is developed to create bumpless performance. Finally, the XV-15 is chosen as a prototype to illustrate the effectiveness of this developed control method.
