High-frequency noise power gain online tracking method for high-order control strategy parameter adjustment

According to the high-frequency noise power gain online tracking improvement method and system suitable for high-order control strategy parameter adjustment, online calculation of the high-frequency noise power gain is completed through noise interference signals contained in signals, and the signals generally contain high-frequency noise interference signals in the actual process. The high-frequency noise power gain of the high-order advanced observer is tracked in real time and controlled to be given by a preset number of high-frequency noise power gains, the performance of the high-order advanced observer is controlled to be in an optimal state, and the influence on online work of the high-order advanced observer is small. 本发明提供一种适用高阶控制策略参数调节的高频噪声功率增益在线跟踪改进方法及系统，利用信号中含有的噪声干扰信号完成高频噪声功率增益的在线计算，在实际过程信号中普遍含有高频噪声干扰信号，通过将所述高阶超前观测器的高频噪声功率增益实时跟踪控制到预设数的高频噪声功率增益给定，将所述高阶超前观测器的性能控制在最佳的状态下，并且对所述高阶超前观测器的在线工作影响较小。
