Abstract

The present invention provides an improved method and system for automatic tracking of high-frequency noise amplitude gain, which is used to improve a high-performance look-ahead observer, by automatically tracking and controlling the high-frequency noise amplitude gain of the improved high-performance look-ahead observer to a preset Given a given high-frequency noise amplitude gain, the performance of the improved high-performance look-ahead observer is controlled at the best state, and the online work of the improved high-performance look-ahead observer is less affected.

Description

technical field [0001] The invention relates to the technical field of thermal power unit process control, in particular to an automatic tracking improvement method and system for high-frequency noise amplitude gain. Background technique [0002] In the field of process control of thermal power units, using advance observation to obtain advance information of process response is of great significance for improving process control performance. In 2019, "Acta Automation China" published a paper "In the Field of Industrial Process Control: Progress and Prospect of Basic Control Technology" in China National Knowledge Network [www.cnki.net] for short, and released a high-performance advanced observation High performance leading observer (HPLO), a breakthrough in the advanced observation mechanism. The high-performance look-ahead observer can be used alone. However, there is a problem of noise interference amplification in advanced observation, mainly high-frequency noise inter...
