微燃机三联供机组的多变量鲁棒自适应负荷跟踪控制
Robust Adaptive Controller for Multivariable Load Tracking in MGT-LiBr CCHP
摘要
Abstract
In order to improve the large-range multiple-load following capability of the micro gas turbine-LiBr double effect absorption refrigerating machine combined cooling,heating and power system (MGT-LiBr CCHP) in the presences of disturbances,this paper proposed a novel L1 robust adaptive control whose design method is improved by using Hammerstein model.First,in this method,the block-oriented Hammerstein modeling is adopted to build the nonlinear dynamic simulation model of controlled systems.Then an assumption of the multivariable non-affine L1 robust adaptive control is solved out by making use of the particular structure of Hammerstein model and thus some reliable controller parameters are obtained.Based on the way,a cooling,heating and power load-tracking controller was built and verified on a series of simulation scenarios.The results demonstrate that the controller can track large-range multiple-load changes well and achieve fast adaptation,robust stability and effective disturbance rejection.Therefore the proposed robust adaptive control strategy provides an advanced alternative solution for maintaining reliable operations of terminal integrated power supply systems.关键词
