提出了一种适用于空空导弹带推力矢量的模糊变结构控制．推力矢量控制的引入可明 显提高导弹的机动性和敏捷性．所设计的变结构控制律由线性控制和非线性控制两部分组成，这 样可通过气动舵面和推力矢量控制机构来实现．考虑到导弹在进行超机动飞行时，气动参数变化 剧烈并且难以估计，因而在控制律中引入了模糊控制规则来增强系统对气动参数变化的适应性和 鲁棒性，同时还有效减弱了一般变结构控制系统的抖颤问题．数字仿真表明了其有效性．
A fuzzy variable structure control which is suitable for thrust vector of air-to-air missile belt is proposed. The introduction of thrust vector control can significantly improve the mobility and agility of missiles. The designed variable structure control law consists of two parts: linear control and nonlinear control, which can be realized by pneumatic control surface and thrust vector control mechanism. Considering the violent and unpredictable aerodynamic parameters of the missile during super-maneuvering, the fuzzy control rules are introduced into the control law to enhance the adaptability and robustness of the system to the aerodynamic parameters changes, and also to reduce the general variable Structural control system dither problem. Digital simulation shows its effectiveness.
