摘要
在导弹采用面对称构型或采用冲压发动机的情况下,倾斜转弯(BTT)方式能实现大过载和优化的发动机性能。针对采用BTT转弯方式带来的三通道耦合问题,提出解耦及参数的解析设计方法。首先对导弹动力学模型中的耦合因素进行分析,针对各耦合因素提出协调控制方法实现解耦,并针对解耦方法提出相关参数的解析设计方法。该方法能实现三通道的解耦,从而实现对制导指令的精确跟踪。数值仿真结果表明了该方法的有效性。
When the missile adopts plane symmetry configuration or ramjet,the large payload and optimal engine performance can be achieved by using the bank-to-turn（ BTT） method. This paper focuses on the coupling problem introduced by the adoption of BTT turning pattern,and a kind of decoupling method including the analytical parameters solution is proposed. The coupling factors contained in the missile dynamic equations are discussed. The decoupling strategy corresponding to each coupling factor is proposed,and the parameters in the controller are designed in analytical manner. This method can realize the decoupling for three channels of missile dynamics,so as to realize the precise tracking of the guidance command. Numerical simulation results validate the effectiveness of the scheme proposed.
