To overcome disturbance problem of hedgehopping over the sea, variable structure method is proposed. The central content in this paper is the design of missile altitude control system with variable structure. The research has practical meaning.

With the continuous development of technology of low-level/hedgehopping attack weapons,air-defense missile fuze is facing more and more strong ground and sea clutter interference.

PID control has been successfully used in many fields such as aviation, spaceflight, missile and other industry control system. The study object in the thesis is missile that flies hedgehopping over sea at minimum altitude. Many interference problem must be solved when missile flies at minimum altitude, otherwise the missile would be dangerous of bumping into the sea under the circumstances of bad weather and wave. The different kinds of interference factors are contradictions with requirements of control system, which can not be solved by PID control.
