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 the speed of hypersonic missile overloading control system, an adaptive sliding mode dynamic surface control method is proposed, and the design of overload control system is carried out by this method. By introducing the virtual control volume, this method overcomes the shortcomings of dividing the fast and slow variables in the inner and outer ring designs and improves the tracking speed of the overload control system. At the same time, the uncertainties in the system are studied. The adaptive sliding mode control algorithm is used to estimate the boundary of the uncertainties, which guarantees the asymptotic stability of the closed-loop system. The simulation results show that the proposed adaptive sliding mode dynamic surface control method has good control performance.
