| 摘 要： | 证明了一种N阶线性跟踪一微分器的收敛性。由于该线性跟踪一微分器的结构参数和跟踪性能对噪声和对象有一定的敏感度和依赖性，采用自适应遗传算法对三阶线性跟踪一微分器的结构参数进行了优化，以期获得较好的参数匹配，提高跟踪预测的精度和速度。将优化后的三阶线性跟踪一微分器用于电力系统参考相角预测研究中，仿真结果证明，优化后的三阶线性跟踪一微分器具有较好的跟踪性能和预测精度，满足电力系统相角预测的要求。

| Abstract: | An N-order tracking differentiator is put forward, then its convergence is proved. Because the structure parameters of the LT-D varies with different objects, an adaptive genetic algorithm is used to refine a 3-order's structure parameters for a better parameters matching, then the refined 3-order LT-D is used to predict the reference phase angle in the electric power system. The simulation research shows that the refined 3-order tracking differentiator has fine tracking ability and good prediction precision that can meet the needs of the prediction of reference phase angle required in the electric power system. It is also applicable to other high-speed tracking system. |
