  2. Based on optimal control theory and singularly perturbed theory, a singularly perturbed midcourse guidance law that guarantees air - to - ground missiles to ascent quickly is proposed. this new guidance law is a composite control law consisting of three parts : optimal climbing control using variable weighting factor method, minimum energy cruising phase control and minimum energy switching phase control. moreover, a new control logic is designed in order to remove influence of climbing control on switching phase. simulation results of a certain type of air - to - ground missile are presents. it is shown that, with simple control algorithm and feasible onboard implementation, this law not only guarantees air - to - ground missiles to ascent quickly, but also satisfies the requirements of midcourse phases. the studies have important theoretical meaning and great value of engineering application

    為滿足實際作戰的要求,基於最優控制理論和奇異攝動方法,提出了一種可保證中遠程空地導彈快爬升到最優高度的中制導律.它由變系數最優爬升控制,最小能量巡控制和最小能量下控制組成.為了減小爬升段控制對下段的影響,提出了一種新的控制邏輯.最後針對某型空地導彈進了模擬.結果表明,該中制導律較好地滿足了中遠程空地導彈在中制導段的要求.本文的研究結果具有較好地工程參考價值
