摘要
为满足巡航导弹大角度机动、大空域飞行的要求,消除由此带来的高度非线性、参数不确定等对控制性能的影响,基于双滑模变结构方法,设计了巡航导弹纵向通道控制器。基于奇异摄动理论,将导弹系统分为快速变化的内环和慢速变化的外环,采用双滑模变结构方法设计了内外环控制器,非线性仿真结果表明,方法能够快速有效跟踪参考轨迹,满足控制系统性能要求。
To satisfy the demand of large angle maneuver and greater aerospace flight for cruise missile, and, to eliminate the influence of highly nonlinearity and parameter uncertainty to the control efficiency, the longitudinal controller of cruise missile is designed based on double sliding mode variable structure theory. Firstly, the variables are divided into fast variable in inner loop and slow variable in outer loop; then, using the double sliding mode variable structure method designs the inner and outer loop controller; at last ,nonlinear simulation results demonstrate the method proposed in this article can track reference trajectory efficiently, and fulfill the need of control system.
