Adaptive Dynamic Surface Control for Integrated Missile Guidance and Autopilot

International Journal of Automation and computing 2011年第1期8卷 122-127页

Integrated guidance and control for homing missiles utilizing adaptive dynamic surface control approach is considered based on the three channels independence design idea. A time-varying integrated guidance and control model with unmatched uncertainties is first formulated for the pitch channel, and an adaptive dynamic surface control algorithm is further developed to deal with these unmatched uncertainties. It is proved that the proposed feedback controller can ensure not only the accuracy of target interception, but also the stability of the missile dynamics. Then, the same control approach is further applied to the control design of the yaw and roll channels. The 6-degree-of-freedom （6-DOF） nonlinear missile simulation results demonstrate the feasibility and advantage of the proposed integrated guidance and control design scheme.

This paper develops a sliding mode control（SMC） approach for a class of uncertain nonlinear systems with unmatched uncertainties/*** newly proposed method is based on a novel fixed-time convergent sliding mode disturbance observer which can estimate the unmatched disturbance in a fixed time（time whose upper estimate is independent of the initial conditions）.By designing a novel sliding surface based on the disturbance estimation,a disturbance-observer based SMC method can counteract the unmatched *** verify the validity of the proposed approach.
