摘要
为了提高超声速导弹过载控制系统的快速性,提出了一种自适应滑模动态面控制方法,并采用该方法进行了过载控制系统的设计。通过引入虚拟控制量,该方法克服了内外环设计中需要划分快、慢变量的缺点,提高了过载控制系统的跟踪速度。同时,对系统中存在不确定量的情况进行了研究,采用自适应滑模控制算法对不确定量的边界进行了估计,保证了整个闭环系统的渐近稳定性。仿真结果表明,所提出的自适应滑模动态面控制方法具有良好的控制性能。
In order to improve speediness of overload control system of a supersonic missile, this paper presents an adaptive sliding-mode dynamic surface control approach. The overload control system of a supersonic missile is designed by this approach. With the introducing of virtual control variables in this approach, this approach overcomes the disadvantage of partitioning fast and slow variables in the inner-outer loop design, and the tracking speed of the overload control system is increased. The case of the system having uncertainty is researched. The adaptive sliding-mode control approach is adopted to estimate the bound of uncertainty, which ensures the asymptotic stability of the whole close-loop system. Simulation results show that the presented adaptive sliding-mode dynamic surface control approach has good control performance.
