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.
