brain tumor detection using matlab

This circuit uses the AC6 block of SimPowerSystems™ library. It models a permanent magnet (PM) synchronous motor drive with a braking chopper for a 3HP motor. The PM synchronous motor is fed by a PWM voltage source inverter, which is built using a Universal Bridge Block. The speed control loop uses a PI regulator to produce the flux and torque references for the vector control block. The vector control block computes the three reference motor line currents corresponding to the flux and torque references and then feeds the motor with these currents using a three-phase current regulator.

永磁同步电机空间矢量控制仿真模型,控制效果不错，可以作为参考模型(PMSM SVPWM SIMUINK MODEL)

基于python的二次开发案例。1、所有的代码均可以先在AbaqusCAE中操作一遍后再通过rp文件读取，然后再在此基础上进行相应的修改； 2、Python是一种解释性语言，读起来非常清晰，因此在修改程序的过程中，不存在程序难以理解的问题； 3、Python是一种通用性的、功能非常强大的面向对象编程语言，有许多成熟的类似于Matlab函数的程序在网络上流传，为后期进一步的数据处理提供了方便。(Python-based secondary development case)

说明：  利用最速下降法可以求得非线性方程的最优解，运算过程简单易懂。(By using the steepest descent method, the optimal solution of nonlinear equation can be obtained, and the operation process is simple and easy to understand.)
