Abstract

The invention provides an automatic tracking method and system for improving the high-frequency noise power gain of a high-performance look-ahead observer. The noise interference signal contained in the signal is used to complete the online calculation of the high-frequency noise power gain. The actual process signal generally contains high High-frequency noise interference signal, by automatically tracking and controlling the high-frequency noise power gain of the improved high-performance advanced observer to a preset number of high-frequency noise power gain, the performance of the improved high-performance advanced observer is controlled at In the best state, it has less impact on the online work of the improved high-performance look-ahead observer.

Description

technical field [0001] The invention relates to the technical field of thermal power unit process control, in particular to an automatic tracking method and system for improving the high-frequency noise power gain of a high-performance advanced observer. Background technique [0002] In the field of thermal power unit process control, the use of advance observation can obtain advance information of process response, which is of great significance for improving process control performance. In 2019, the Chinese Journal of Automation published the paper "In the Field of Industrial Process Control: Advances and Prospects of Basic Control Technology" on CNKI published a high performance leading observer (High performance leading observer, HPLO), which has made a breakthrough in the advance observation mechanism. The high-performance look-ahead observer can be used alone. However, the advance observation has the problem of noise interference amplification, mainly high frequency ...
