Parameter design of integrated altitude control system using steady state genetic algorithm

In the design of missiles with supersonic speed at minimum altitude, a kind of integrated altitude control scheme of radio altimeter+inertial altitude system was proposed to solve the problem of hedgehopping over the sea. The choice of parameters is the key point in the design of integrated altitude control system. We applied the steady state genetic algorithm to solve the problem. The design and implement of steady state genetic algorithm on the integrated altitude control system was discussed in this paper. Simulation experiment shows that the anti-disturbance ability and the response speed of integrated altitude control system can be improved apparently by using optimized parameters.
