导弹复合控制系统的切换控制器设计

摘要

为了满足现代高科技的作战要求,导弹控制系统可以采用直接力/气动力复合控制的方法,来增加导弹的机动性和精确性.首先对导弹建立俯仰通道内的数学模型,并运用切换控制方法分别对气动力和直接力的控制律进行设计.其次为了提高气动力控制的精度,引入了指数趋近律,结合模糊控制的方法,对直接力系统中的不确定参数进行优化设计,提高了直接力控制的有效性.最后利用仿真对复合控制系统控制器的设计结果进行了验证.%In order to meet the requirements of modern high-tech warfare,reaction-jet/aerodynamic compound control and guidance technology can be used in missile control system to increase the mobility and accuracy of missiles.Firstly,the mathematical model of the missile in pitch plane is formulated,and the control law of reaction-jet and aerodynamics is designed separately by using switching control system.Secondly,the index reaching law and fuzzy control method are introduced to improve the accuracy of aerodynamic control.Simultaneously,the uncertain parameters design is optimized to enhance the effectiveness of reaction-jet control.At last,the simulation results show that the proposed scheme is very effective.
