提取语音信号的基音周期的matlab程序(Extract the pitch period of the voice signal matlab program)

The induction motor is fed by a current-controlled PWM inverter which is built using a Universal Bridge block. The motor drives a mechanical load characterized by inertia J, friction coeficient B, and load torque TL . The speed control loop uses a proportional-integral controller to produce the quadrature-axis current reference iq* which controls the motor torque. The motor flux is controlled by the direct-axis current reference id*. Block DQ-ABC is used to convert id* and iq* into current references ia*, ib*, and ic* for the current regulator. Current and Voltage Measurement blocks provide signals for visualization purpose. Motor current, speed, and torque signals are available at the output of the Asynchronous Machine block.

基于fft的匹配追踪算法，且ff与tMATLAB中自带的源程序不尽相同(Fft-based matching pursuit algorithm, and ff the source code comes with tMATLAB in different)

不选主元的高斯消元法，用于求解线性方程组，很好用！基于c++编写。(Do not choose the principal component of the Gauss elimination method for solving linear equations, very good use! Prepared based on c++.)

用matlab语言对汽车动力经济性进行仿真(very good)

说明：  第二种孤岛运行的控制是采用下垂控制（droop控制），Droop控制就是用来模拟频率一次调整。通过控制电力电子逆变器来实现。(The second kind of island operation control is droop control, Droop control is used to simulate a frequency adjustment. It is realized by controlling the power electronic inverters.)
