代码说明:

      应用LSE 算法估计载波频率和相位,又称为锁相环,产生具有特定频率和相位的正弦信号,使用接近真值的参数值为初值,测试迭代估计算法,使用初值和迭代算法,估计频率和相位值,并根据估计出的频率和相位值画出估计得正弦波。将正弦波真值和估计值画在同一个图中,每更新一次,重新绘制两个波形,最终需要画出演示视频中的效果:估计出的波形逐步靠近真正的波形。

    说明:  模糊控制器的设计不依靠被控对象的模型,而是依靠控制专家或操作者的经验知识。模糊控制的突出优点是能够比较容易地将人的控制经验溶入到控制器中,但若缺乏一定的控制经验,很难设计出高水平的模糊控制器。而且,由于模糊控制器采用了IF-THRN控制规则,不便于控制参数的学习和调整,使得构造具有自适应的模糊控制器较困难。 自适应模糊控制是指具有自适应学习算法的模糊逻辑系统,其学习算法是依靠数据信息来调整模糊逻辑系统的参数。一个自适应模糊控制器可以用一个单一的自适应模糊系统构成,也可以用若干个自适应模糊系统构成。与传统的自适应控制相比,自适应模糊控制的优越性在于它可以利用操作人员提供的语言模糊性信息,对具有高度不确定因素的系统尤为重要(Fuzzy controller design does not rely on the controlled object model, but on control expert knowledge or experience of the operator. Highlight the advantages of fuzzy control is the ability to more easily control the experience of people integrated into the controller, but if a certain lack of control experience, it is difficult to design a high-level fuzzy controller. Moreover, since the fuzzy controller using the IF-THRN control rules is not easy to learn and adjust the control parameters, making construction more difficult adaptive fuzzy controller. Adaptive fuzzy control refers to the fuzzy logic system with adaptive learning algorithm, which is to rely on the data information learning algorithm to adjust the parameters of fuzzy logic systems. An adaptive fuzzy controller with a single adaptive fuzzy system configuration, you can also use a number of adaptive fuzzy system structure. Compared with the traditional adaptive control, adaptive fuzzy control advantages is that it can tak)
