永磁同步电机的模糊矢量控制仿真模型，拿出来和大家分享。(simulation model of PMSM based on fuzzy FOC)

这是我找到的谐波小波程序，国内没有哦，希望对搞这方面的朋友有所帮助，站长一定要加分哦(I find this is the harmonic wavelet procedures, domestic Oh no, and I hope to engage in this regard friends help, director must oh points)

This paper discusses the impact of HVDC on Power System Stability and proposes a new control mechanism based on Fuzzy set theory to augment dynamic performance of a multi-machine power system. To have good damping characteristics over a wide range of operating conditions, deviations in speed and acceleration of the machines are chosen as the input signals to the fuzzy controller. These input signals are first characterized by a set of linguistic variables using fuzzy set notations .The fuzzy relation matrix allows a set of fuzzy logic operations that are performed on controller inputs to obtain the desired output. The effectiveness of the proposed controller is demonstrated by a multi-machine system example. The performance of this fuzzy controller, in comparison to the conventional fixed gain controller, demonstrates the efficacy of this new fuzzy PID controller. Index Terms—HVDC, Eliminated variable

this is a code for triangular membership function in fuzzy logic

用于求解不可压ns方程的动量守恒计算方程的核心部分，采用了二维对称调用的技术。(Ns for solving incompressible equation of momentum conservation equation of the core part of the calculation, using a technique called two-dimensional symmetry.)

A Rayleigh distribution is often observed when the overall magnitude of a vector is related to its directional components.

x0 = ones(2,2) Make a starting guess at the solution options = optimset( Display , off ) Turn off Display [x,Fval,exitflag] = fsolve(@myfun,x0,options) The solution is x = -0.1291 0.8602 1.2903 1.1612 Fval = 1.0e-009 * -0.1619 0.0776 0.1161 -0.0469 exitflag = 1 and the residual is close to zero. sum(sum(Fval.*Fval)) ans = 4.7915e-020

The software implements particle filtering and Rao Blackwellised particle filtering for conditionally Gaussian Models. The RB algorithm can be interpreted as an efficient stochastic mixture of Kalman filters. The software also includes efficient state-of-the-art resampling routines. These are generic and suitable for any application.(The software implements particle filteri Vi and Rao Blackwellised particle filtering az r conditionally Gaussian Models.
