论文摘要
本文为复位控制系统提供了一种新型的自适应馈电控制器设计。前馈和复位反馈控制的组合有望高性能，因为进料可以保证参考跟踪，而非线性反馈元素则拒绝干扰。为了克服不可避免的模型不匹配，馈电控制器适应以提高参考跟踪中的精度。如果现有的自适应前进控制器不能保证在存在重置的情况下收敛，则此工作为基于融合和不同自适应区域的新型自适应定律，以实现良好的跟踪。实验结果证明了这种新方法的主张优势。
This paper presents a novel adaptive feedforward controller design for reset control systems. The combination of feedforward and reset feedback control promises high performance as the feedforward guarantees reference tracking, while the non-linear feedback element rejects disturbances. To overcome inevitable model mismatches, the feedforward controller adapts to increase precision in reference tracking. Where linear existing adaptive feedforward controllers do not guarantee convergence in the presence of reset, this work presents a novel adaptive law based on converging and diverging regions of adaptation to achieve good tracking. Experimental results demonstrate the claimed advantage of the novel method.
