| 中文摘要 |
| 对于带有不匹配干扰的动态系统, 设计具有高资源利用率的抗干扰控制算法具有重要意义. 本文在双事件触发机制框架下, 研究了非匹配干扰系统的积分滑模抗干扰控制以及动态性能分析问题. 首先, 基于增广模型构建干扰观测器, 实现对未知不匹配干扰的动态估计. 为了降低数据冗余并保证传输的同步性, 以反馈状态及干扰估计的单触发条件为基础, 本文构建了“先到同触发”的双事件触发理论框架. 在此框架下, 设计积分滑模面和对应的双触发抗干扰控制器, 保证被控系统的状态收敛到滑模面. 基于Lyapunov稳定性分析方法, 计算控制器和观测器增益,保证增广闭环系统具有良好的稳定性和动态跟踪性能. 进一步分析了由触发引起的Zeno现象将不会发生. 最后, 基于典型的A4D模型进行仿真验证, 仿真结果表明本文所提的方法具有良好的抗干扰性能. |
| 英文摘要 |
| For the dynamic systems with mismatched disturbances, it has an important significance to design antidisturbance control algorithm with high resource utilization. Under the frame of double event-triggered mechanism, this paper discusses integral sliding mode anti-disturbance control and dynamic performance analysis for the unmatched disturbance systems. Firstly, based on the augmented model, the disturbance observer is constructed to realize the dynamical estimation of unknown mismatched disturbances. In order to reduce data redundancy and ensure synchronization of transmission, based on the single trigger condition of feedback state and disturbance estimation, a double event-triggered framework is proposed with the principle of first-arrival and same-trigger. Based on this, both the integral sliding surface and the corresponding double event-triggered anti-disturbance controller are designed to guarantee the controlled system convergence to the pre-designed sliding surface. Based on the Lyapunov analysis method, the gains of controller and observer are calculated, which ensures the favorable stability and dynamic tracking performance of the augmented system. Further, it is analyzed that the Zeno phenomenon caused by the trigger will not occur. Finally, a typical A4D model is used for the simulation verification, and the simulation results show that the proposed method has satisfactory anti-disturbance performance. |
