基于maglab/simulink平台设计的利用duffing振子检测微弱正弦信号，非常好的一个源程序，自己亲自调试，运行在matlab2012b上没有问题，仿真步长0.01s,采用RK四阶算法。若有问题，欢迎指教(Based maglab/simulink platform using duffing detect weak sinusoidal oscillator signal, a very good source, personally commissioning, operation without problems on matlab2012b, simulation step 0.01s, using the fourth-order RK algorithm. If questions, please advise)

自然哲学之数学原理，伟人的杰作，可以看看(Mathematical Principles of Natural Philosophy, the great masterpiece, you can see)

用C语言编写的在Simulink环境下对3相交流逆变器进行数值仿真的S函数源代码。该仿真源代码的一个独特之处就是：利用全新的数学模型能够对逆变器相间换流的动态过程进行仿真，这是目前其它同类模型中绝对没有的独特支出，可以用来精确仿真永磁无刷直流电机转矩的动态特性，执行效率很高。(C language in the Simulink environment for three-phase inverter for the numerical simulation letter S several sources. The simulation source code a unique way : the use of new mathematical model to the phase inverter for the dynamic process flow simulation, This is similar to other models, there is no unique expenditures, Simulation can be used for precision brushless DC motor torque to the dynamic characteristics of high efficiency.)

虚拟同步机的并网simulink模型，主要是VF+DROOP CONTROL的结合，解决了虚拟阻抗的加入(Virtual machine synchronization and network simulink model is mainly a combination VF+DROOP CONTROL solve the virtual impedance added)

A typical example of using the dSPACE system for electrical drives simulations is described in [9] and for wind energy conversion systems (WECS) in [10]. However, before the real-time implementation, the Control part has to be validated by simulation using a plant model. This model could be developed using either the Simulink transfer functions or the PLECS toolbox.
