摘要
反馈控制系统的Delta算子理论在高速信号处理与数字采样控制领域具有重要作用．本文对Delta算子方法的研究现状与存在问题进行综述，内容涉及Delta算子模型描述与转换、系统辨识与状态估计、自适应控制与预测控制、鲁棒控制与H∞控制、数字滤波器实现等方面，并探讨了将来的发展方向．
In this paper,a tutorial introduction to the delta operator theory for feedback control system isprovided,which plays the important role in high speed signal processing and digital control systems. Delta operator is used as a framework to unify the continuous-time and discrete-time system theories such as systemidentification and state estimation,adaptive control and predictive control,robust control and H∞ control. Realization of digital filter is also discussed and the important topics for the further study based on delta operator are pointed out.
