对最小相位系统的性能研究以及DMC的仿真实例。(The simulation study of the performance of the system and the minimum phase of DMC.)

由方波代替了SPWM，实现了SPWM电机调速(Replaced by a square-wave SPWM, motor speed to achieve the SPWM)

说明：  免疫克隆算法求函数最优值，人工免疫具有分布式、自学习、自适应、自组织和鲁棒性等特点，具有强大的信息处理和问题求解能力。免疫克隆选择算法是一种受生物免疫系统克隆选择原理启发而设计的新型智能优化算法。它结合了问题的先验知识和生物免疫系统的自适应能力，因而在信息处理方面具有较强的鲁棒性，在搜索过程中能更好地收敛到全局最优解。(Immune clone algorithm to find the optimal value of function)

异步电机矢量控制仿真 波形很好 真的(Simulation waveform vector control induction motor is really good)

This simulation script set allows for an OFDM transmission to be simulated. Imagetx.m generates the OFDM signal, saving it as a windows WAV file. This allows the OFDM signal to be played out a sound card and recorded back. Imagerx.m decodes the WAV to extract the data.
