Abstract:

In order to design a low cost high performance digital overload control system for winged missile by common rudder described by first order plant, on the basis of the assumption that the single channel of the missile is a third order plant, the dynamics of the missile were separated into overload subsystem (low speed subsystem), angular rate subsystem (middle speed subsystem), and angular acceleration subsystem (high speed subsystem). And AdamsBashforth numerical approach was used to discrete the subsystems for the design of a discretetime dynamic inversion controller. Desired discretetime dynamics for the subsystems was obtained by using Lyapunov synthesis method and bandwidth parameter selection method was also given. Simulation results demonstrate the rightness and validity.

Key words: control and navigation technology of aerocraft, missile control, overload control, discrete system, timescale separation, dynamic inversion, Lyapunov stability
