模式搜索法源程序。模式搜索方法是求解最优化问题的一种直接搜索方法,它不用目标函数与约束函数的导数信息而只用函数值信息,是求解不可导或求导代价较大的最优化问题的一种有效方法。(Source model search. Pattern search method for solving optimization problems is a direct search method, it should not be the objective function and constraint function information of the derivative function only information is the solution of non-derivative or derivative of the cost of a larger optimization problem of a effective way.)

针对永磁同步电机常规直接转矩控制系统涉及到的问题,例如磁链的准确观测、定子电阻的变化、电压矢量开关表的改进以及滞环控制器的改进等等,本文都作了详细的分析,并提出了改进方案。为了提高系统的性能,本文将空间矢量调制的方法引入了常规直接转矩控制中,并在此基础上,对永磁同步电机无速度传感器问题作了详细的分析,总结了国内外的研究热点,提出了采用转子磁链矢量为基础的永磁同步电机直接转矩控制速度估计方法。仿真结果表明,该方案具有很好的动、静态特性。(Firstly, the paper analyzes the principle of direct torque control of permanent magnet synchronous motor and elaborates the impact of space voltage vector of the stator flux and the electromagnetic torque.Secondly, the paper introduces direct torque control of permanent magnet synchronous motor SVPWM technology.Under the same hardware conditions,the system can obtain More continuous voltage space vector by taking advantage of SVPWM.The simulation results show the program not only keeps the direct torque control fast dynamic response, but also reduce the motor torque ripple.)

07.-Chapter-4---Fourier-Transform
The Fourier transform, named for Joseph Fourier, is an integral transform that operates on the mathematical representation of a function in time and produces a function in frequency. The term Fourier transform customarily refers to both the transform operation and to the function it produces.
