【摘要】 RFFT(Recursive Fast Fourier Transformation)是一种基于快速付立叶变换的递推算法。由于输入数据的数目和递推次数可任意选择,因此本算法具有很大的灵活性,适用于时变系统和自适应控制系统的在线辨识。本文介绍了采用 RFFT 算法的微计算机辨识系统并给出了实验结果。更多还原

【Abstract】 RFFT is a recursive algorithm based on Fast Fourier Transformation.Because ofthe arbitrary choice of the section of input sequence and the times of recursion,thismethod is more flexible and useful in time-varying spectrum analysis and on-lineidentification of self-adaptive control system.A microcomputer system with RFFTalgorithm for identification is given in this paper.更多还原
