信号与系统试验报告
离散傅立叶变换（DFT）和频谱分析
一、实验内容
1、实验题目
（1）编写DFT、IDFT程序，并验证其正确性（提示：可利用冲激函数进行验证）。
（2）计算信号f(t)=e-at2sin(2∏ft)的离散傅立叶变换（DFT），求其振幅谱，相位谱、振幅最大值对应的频谱（检测主频）以及对发f(t)进行DFT变换的结果实现IDFT变换，并画出图形。
参数选择如下：频率f =30HZ，a=f 2㏑(M),M=2.5
2、通过实验理解信号振幅谱、相位谱的物理意义，掌握DFT、IDFT算法的实现方法。()

Under the circumstances of pure lag in feedback control system and the imprecision of the controlled object model, the fuzzy logic and pure lag compensation theory is used to design a Fuzzy PI-Smith control system . By the Simulink toolbox and Fuzzy logic toolbox of MATLAB, the system has been simulated. The simulation results show that the Fuzzy PI-Smith system has faster response speed and smaller overshoot than the traditional PI-Smith system.The explicit formulation of Fuzzy PI-Smith system is derived, and it lay the basis for the practical application of control algorithms.
