中文摘要:
      为了使无模型自适应控制(Model-Free Adaptive Control,MFAC)更好地解决伴有噪声干扰系统的控制问题,在无模型自适应控制方法的基础上,针对伴随噪声干扰的系统进行分析研究,引入带有滤波作用的跟踪微分器,在反馈过程进行滤波操作,提出一种基于改进跟踪微分器(Improved Tracking Differentiator,ITD)的无模型自适应去噪控制方法,同时给出了该算法的收敛性证明. 并通过仿真证明了本文改进的控制方法可以快速跟踪给定信号并且具有良好的抵抗噪声干扰特性. 最后,将其应用在循环流化床锅炉汽包水位的控制中.
英文摘要:
      In order to make the model-free adaptive control(MFAC) better solve the control problem with noisy system, this paper examines the noise system and applies improved tracking differentiator in MFAC. Filtering is performed in the feedback process, and a MFAC method based on improved tracking differentiator(ITD) is proposed. The convergence of the algorithm is also proved. The simulation experiment proves that the improved control method can quickly track a given signal and has good resistance to noise interference. Finally, it is applied to the control of the drum water level of circulating fluidized bed (CFB) boiler.
