摘　　要：在复杂的工业生产过程中,控制系统不可能工作在理想的状态,其总会受到外界各种各样的影响,比如,在对反馈信号进行测量时,控制系统不可避免地会受到高斯测量噪声以及非高斯测量噪声的影响;为了降低测量噪声的影响,通常会将各种各样的滤波技术应用到控制系统中来,以此提升控制系统的性能;以孤岛微电网的频率控制系统为研究对象,考虑了当反馈回路有高斯分布测量噪声和非高斯分布测量噪声的两种情况,针对这两种测量噪声信号在模型中引入了动态数据校正滤波技术,分别对比了有无使用动态数据校正滤波技术时电网的频率偏差的方差大小,以此验证了动态数据校正滤波技术在微电网反馈控制回路中可有效抑制测量噪声的影响从而提升微电网频率控制性能。In the complex industrial process,the control system cannot work in an ideal state and It will always be affected by all kinds of external influences.For example,when the feedback signal is measured,the control system will inevitably be affected by the Gaussian distributed and non-Gaussian distributed measurement noise.To reduce the influence of measurement noise,various filtering techniques are usually used to the control system to improve the performance of control system.Frequency control system of microgrid is taken an the research object,considering that the feedback loop has the Gaussian distributed and non-Gaussian distributed measurement noise,for two kinds of measurement noise signals,the dynamic data reconciliation based the filtering technology is introduced in the model.The power grid frequency deviation is used for the comparison with and without the use of the dynamic data reconciliation based the filter technology.The results show that the dynamic data reconciliation based the filter technology can effectively suppress the influence of measurement noise in the feedback control loop of the microgrid,which improves the frequency control performance of the microgrid.
