摘　　要：随着飞行任务的变化,对机动飞行器进行速度控制时的运动姿态提出了新的要求。为了提高速度控制精度以及拓展该方法在多种控制方式中的应用范围,首先,利用高斯伪谱法(Gauss Pseudospectral Method,GPM)生成理想速度曲线,为飞行器作速度控制提供可靠的速度参考曲线;然后,提出了带倾侧角约束的侧滑转弯(Skid To Turn,STT)形式以及倾斜转弯(Bank To Turn,BTT)形式的速度控制设计方法。仿真分析表明,本文提出的方法,能够实现对再入飞行器落速的精确控制,同时实现带倾侧角约束STT形式及BTT形式的机动飞行器速度控制。With the change of the flight mission,the new pose requirement in the velocity control method is proposed.The research aims to improve the accuracy of the velocity control method and expand its application scope in different control method.The ideal velocity control curve is generated by using the Gauss Pseudospectral method,which is offered as the reliable velocity reference curve.Then,the velocity control method in STT style with the constraint of bank angle and BTT style is derived.The simulation results show that the proposed method can control the final velocity of reentry vehicle accurately,and realize the velocity control in STT style with the constraint of bank angle and BTT style.
