摘　　要：采用量子粒子群算法辨识得到机炉协调控制系统的全局线性参数变化(LPV)模型,然后通过极值分解组合得到多胞LPV模型。针对多胞LPV模型,在鲁棒H_(∞)/H_(2)变增益控制中引入松弛变量,设计了保守性更低的机炉协调控制系统鲁棒控制器。结果表明:所设计的控制器具有良好的控制效果。The global linear parameter varying(LPV)model of a boiler-turbine coordinated control system was identified by the quantum particle swarm optimization algorithm.A polytopic LPV model was obtained by the extremum disassembling and assembling.Aiming at the polytopic LPV model,the relaxation variable was introduced into the robust H_(∞)/H_(2)gain-scheduling control,and a less conservative robust controller for the coordinated control system was designed.Results show that the designed controller has good control effect.
