过热汽温系统改进自抗扰控制及其工程应用研究
Research on modified active disturbance rejection control and its engineering application for superheated steam temperature system
摘要
Abstract
Superheated steam temperature is crucial for safety and economy of coal-fired power units.However,the large inertia and strong uncertainty of superheated steam temperature system make it difficult to control.To solve these difficulties,a cascade control structure based on modified active disturbance rejection control is proposed.The inner loop uses a conventional PI controller and the outer loop uses a modified active disturbance rejection controller.An engineering tuning method for modified active disturbance rejection control is provided,and a response curve to optimize the compensation time constant is designed to address the difficulty of obtaining the compensation time constant.Finally,the advantages of the proposed control strategy in tracking and disturbance rejection performance under large-scale variable loads are verified through comparative simulations and practical engineering applications.The operational data of engineering applications shows that the proposed method can ensure smaller maximum positive and negative deviations,average absolute deviation,and deviation standard deviation,which has significant advantages and potential for engineering applications.关键词
