Code to operate with Midlin equation to extract inharmonic frequencies

数字信号处理，离散时间系统的相位、结构与状态变量描述典型题，能更好的理解离散时间系统(Digital signal processing, discrete-time systems the phase, structure and state-variable description of a typical question, can a better understanding of discrete-time systems)

lbg算法用matlab实现。。内有英文文献及相关代码(Lbg algorithm matlab.. There were English literature and relevant code )

说明：  step response of control system

针对常规PID控制不具有自适应能力，对于时变、非线性系统控制效果不佳。提出了将模糊技术与PID控制相结合的控制方式，设计模糊控制器。(Conventional PID control with adaptive capabilities, time-varying, nonlinear system control ineffective. Fuzzy and PID control combined control mode fuzzy controller design.)

本程序是EM算法，是参数估计（极大似然估计）方法的数值解法。(This procedure is the EM algorithm, is the parameter estimation (MLE) method of numerical solution.)
