摘要
Abstract
The longitudinal trajectory-correction capability usually varies in a non-monotonic way with the increase of the control start time .The reason of the change trend of the longitudinal trajectory correction capability was analyzed theoretically ,and the discriminant function of trajectory -correction based on perturbation theory was deduced.The optimized method of canards control in longitudinal plane was put forward based on the discriminant function of trajectory correction .The conventional canards control phase was set when the discriminant function of trajectory correction was positive ;the optimized canards control phase was set when the discriminant function of trajectory correction was negative .This method can make sure that the trajectory correction direction is same , so the longitudinal trajectory correction capability is increased greatly .The simulation of one guided mortar projectile with fixed canards was carried out .The simulation result shows that this method can increase the longitudinal trajectory -correction capability with different elevation angles by0-252%.The effectiveness and adaptability of this method on application was testified by Monte-Carlo simulation.关键词
