摘    要:针对传统的侧滑转弯(STT)控制机动能力相对不高和倾斜转弯(BTT)控制在机动上有一定的时延等缺点,以空射导弹为例,将导弹的飞行过程划分为三个阶段,采用混合BTT/STT逻辑将导引头输出的过载信号转换为攻角、侧滑角和滚转角指令信号,并且分别设计了导弹俯仰-偏航通道和滚转通道滑模变结构控制器,使其能够准确跟踪给定的攻角、侧滑角、滚转角指令。为了减小变结构控制器的抖振影响,采用了将切换控制连续化的方法。最后通过仿真验证混合BTT/STT控制逻辑的可行性和变结构控制器设计的有效性。

关 键 词:倾斜转弯  侧滑转弯  滑模变结构  控制器  连续化切换控制

Abstract:To solve the problems that traditional skid-to-turn(STT) control can not perform high g maneuvers and bank-to-turn(BTT) control do not have satisfied response time,three phases are divided appropriately during the missile flight.Hybrid BTT/STT control logic is applied during these phases to transform accelerations to commands of angle of attack,sideslip angle and bank angle.Variable structure methodology is applied in designing of pitch-yaw channel and roll channel controllers aiming to track command signal...
Keywords:BTT  STT  sliding mode  variable structure control  continuous switch control
