Integrated Guidance and Control Design by Combining Backstepping and Sliding Mode Control Methods

In this paper, a novel integrated guidance and control (IGC) approach is designed using the combination of backstepping and sliding mode control methods. In contrast to the traditional methods combining the kinematic and dynamic equations and deriving a state space model as an integrated unit model, the proposed method designs the guidance and control problem in a single loop. This algorithm is robust with respect to the uncertainties in the target acceleration and missile dynamic model. Simulation results using six-degrees-of-freedom simulation aerodynamic model (6DOF) and three-dimension (3-D) engagement show that the proposed IGC design, with guidance and control dynamic synergism, eventuates interception with the maneuvering target.
