When the missile intercepted a maneuvering target, both the missile body';s dynamic nature and its approximate linearization when modeling had effects on the miss distance and guide quality. To solve this problem, the article does not resort to the hypothesis of the linearization near collision course and builds an integrated guide-control model. Basing on sliding mode variable structure theory, the article proposes an integrated nonlinear guide-control strategy which takes into account both missile';s control loop character and guidance loop character. This strategy can effectively resolve escape maneuver of the target so that a favorable guide quality is still achievable even if the control loop is not compensated.
