论文的程序，与大家分享 应用混沌序列对水印信息进行置乱源代码 (Thesis process, and application of chaotic sequences to share information on scrambling watermark source code)

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.)
