Algorithm Design For Planar Missile Guidance

Along with the science and technology development, in the air fight the goal mobility strengthens day by day, if the missile use some classical guidance laws to intercept greatly mobile goal, obviously cannot satisfy the request.The future rencountre urgent need a guidance law which is able to adapt the more complex operational environment, therefore, it has already been an important work which will become currently must carry on urgently to develop and apply the new guidance law.In this paper, the classical guidance law for missile-tracking in parallel close to france, three-point method, proportional navigation law, combined with the geometric aspects of the space of mathematical knowledge, in accordance with the guidance of their different rules of conduct of the algorithm design, simulation results obtained, as well as a brief analysis of simulation results. Modern guidance law for the robust geometric algorithm design method and set the simulation parameters, come to intercept ballistic graphics, the same as in the other simulation parameters, the comparison of proportional navigation law and robustness in different geometric Under the initial direction of missile guidance trajectory angle.Compared with the simulation result, we may see with the classics guidance law compares, the robust geometry method has many merits, for example: The trajectory is straight, resistance target maneuver and disturbance ability, target maneuver has strongly robust and so on to, thus had proven the union modern control theory robust geometry method is one kind has the high accuracy guiding law.
