【摘要】：針對(duì)線性二階濾波器時(shí)間滯后的問(wèn)題,提出了一種LCR正弦跟蹤的變形結(jié)構(gòu)和新型正弦跟蹤的新方法.通過(guò)對(duì)變形結(jié)構(gòu)深入的理論研究和分析后得出,LCR正弦跟蹤器特性的不理想,是造成二階濾波器滯后問(wèn)題的內(nèi)在原因.通過(guò)正交調(diào)幅和正交解調(diào)等技術(shù)構(gòu)造出一種新型的正弦跟蹤器,采用新型正弦跟蹤器構(gòu)造出的新型二階濾波器,具有滯后時(shí)間較小和抗噪聲干擾特性較強(qiáng)等優(yōu)良的線性濾波特性.文中提出的方法屬于一種線性濾波技術(shù),能夠應(yīng)用在控制理論的信號(hào)濾波等方面.通過(guò)數(shù)學(xué)分析、仿真實(shí)驗(yàn)和實(shí)際應(yīng)用等分析了所提出方法的有效性.
[Abstract]:In order to solve the problem of time delay of linear second-order filter, a new method of LCR sinusoidal tracking is proposed in this paper. Based on the theoretical study and analysis of the deformed structure, it is concluded that the characteristic of the LCR sinusoidal tracker is not ideal, which is the internal cause of the second order filter delay problem. A new sinusoidal tracker is constructed by means of quadrature amplitude modulation and quadrature demodulation, and a new second-order filter is constructed by using a new sinusoidal tracker. It has good linear filtering characteristics, such as small lag time and strong anti-noise interference. The proposed method belongs to a linear filtering technique and can be applied to signal filtering in control theory. The effectiveness of the proposed method is analyzed by mathematical analysis, simulation experiment and practical application.
