本文采用经典的和现代的两种控制理论来讨论倾斜转弯(BTT)控制系统的设计。首先讨论倾斜转弯制导指令信号的公式,接着讨论最佳制导的应用,采用线性动态模型求闭环制导指令,然后讨论有关倾斜转弯自动驾驶仪的设计。对倾斜转弯自动驾驶仪设计的传统控制方法和非线性系统求逆方法均进行了讨论。介绍了一种BTT-90°控制导弹截击目标的六自由度(6DOF)仿真的计算结果,截击的目标为轻型、高推重比型战斗机,在仿真计算中也包括了对机动目标跟踪算法。
This article uses both classic and modern control theory to discuss the design of tilt-turn (BTT) control systems. First, we will discuss the formula for tilting guidance commands. Then we will discuss the best guidance application. We will use the linear dynamic model to find the closed-loop guidance instructions, and then discuss the design of the tilting autopilot. The traditional control methods and non-linear system inversion methods of tilting autopilot are discussed. A six degree of freedom (6DOF) simulation of a BTT-90 ° control missile interception target is introduced. The target of interception is a light-weight and high-thrust ratio fighter, and a maneuvering target tracking algorithm is also included in the simulation calculation.
