摘　　要：针对含不确定因素的多输入多输出非线性微分代数系统,提出一种目标全息反馈鲁棒自适应控制方法(robust adaptive control with objective holographic feedbacks,RACOHF).该方法考虑到了系统模型参数的不确定性和外部扰动,同时将外部输入扰动视为模型不确定性参数的变化,在目标全息反馈控制方法的基础上,通过设计模型不确定性部分的自适应调节律,实现多目标的自适应跟踪控制.将该方法应用于中间再热式汽轮发电机组蒸汽调节阀和励磁的协调控制,结果表明,在系统部分参数不确定和存在外部扰动的情况下,所提出方法能确保发电机机端电压和有功功率等目标量在期望的工作点上运行而不发生静态偏移.与目标全息反馈非线性控制(nonlinear control with objective holographic feedbacks,NCOHF)相比,所提出的方法(RACOHF)能更好地协调系统的动、静态性能.A robust adaptive control method with objective holographic feedbacks(RACOHF)is proposed for a multi-input multi-output uncertain nonlinear differential algebraic system.The uncertainty of the system model and the external disturbances are considered by the RACOHF,and the external input disturbances are regarded as changes in uncertain parts of the system model.Then,based on the objective holographic feedbacks control,the adaptive tracking control of multi-objectives is realized through the adaptive adjustment of the uncertain parts of the model.Finally,the RACOHF is applied to the coordinated control of steam valve and excitation of reheat-type turbo-generator sets.Simulation results show that the RACOHF can ensure the control objectives such as generator terminal voltage and active power run at the expected working point without static offset under the condition of uncertain system parameters and external disturbances.Compared with nonlinear control with objective holographic feedbacks(NCOHF),the RACOHF can give better consideration to the dynamic and static performance of the system.
