| 摘 要： | 提出了一种适用于带推力矢量空空导弹的变结构自适应控制器设计方法 ,推力矢量的采用是为了使导弹获得超机动能力以对付强机动目标。所设计的变结构控制律包括两部分,即线性控制部分和非线性切换控制部分,其作用力由气动舵面和非线性反作用喷气装置提供。在设计控制律时引入了对系统参数变化的自适应算法,简化了控制器的设计。数字仿真表明其有效。

| Abstract: | A variable structure adaptive control system for air to air missiles with thrust vectoring control is designed. Thrust vectoring actuators are used for the missiles to get supermaneuver flight ability. The designed control law includes two control parts, i.e. the continuous control part and the discontinuous control part, which are implemented by aerodynamics and reaction jet actuators respectively. Moreover, with consideration that while the missiles are supermaneuvering, the system dynamic parameters are poorly known and rapidly changing, an adaptive estimation algorithm for the system parameter variations is proposed to simplify the control system design. Numerical simulation results are given to illustrate its effectiveness. |
