本文提出了新的结果，在实施离散时间分数阶PI控制器通过使用计算简单和准确的模型降阶为基础的近似分数阶积分。所介绍的方法的主要优点是消除稳态控制误差，功能优于其他有限长度的离散时间分数阶积分器的实现。仿真实验证实了所提出的方法的有效性，无论是在高精度和计算效率的近似介绍。
The paper presents new results in implementation of a discrete-time fractional-order PI controller by use of computationally simple and accurate Model Order Reduction-based approximation of a fractional-order integrator. The main advantage of the introduced method is elimination of the steady-state control error, the feature outperforming other finite-length implementations of discrete-time fractional-order integrators. Simulation experiments confirm the effectiveness of the presented methodology, both in terms of high accuracy and computational effectiveness of the introduced approximation.
