摘要
针对二维弹道修正弹固定舵控制回路易受干扰的问题,提出了一种单向辅助面滑模变结构控制方法,通过对传统滑模进行结构上的改进,增强了滑模控制方法的鲁棒性。可以不借助高阶滑模和边界层滑模的去抖振思想,仅依靠不连续趋近率来保证控制器的无抖振输出,从而实现无抖振的滑模控制。基于该方法设计了二维弹道修正弹姿态控制器,并通过仿真验证了其抗干扰控制性能。
Aiming at the interference that the control loop of the fixed-canard of the two-dimensional Trajectory Correction Projectile,a unidirectional auxiliary surface sliding mode variable structure control method is proposed.Through the structural improvement of the traditional sliding mode,the robust of the sliding mode control method is enhanced.It is possible to ensure the continuity of the controller output by only relying on the discontinuous convergence rate without resorting to the idea of the high-order sliding mode and the boundary layer sliding mode,thereby,it achieves the chatter-free sliding mode control.Based on this method,an attitude controller of two-dimensional Trajectory Correction Projectile is designed and its anti-jamming control performance is verified by simulation.
