将PID 控制与模糊控制的简便性、灵活性以及鲁棒性融为一体,构造了一个参数自整定模糊PID 控制器. 通过模糊控制规则在线调整PID 控制器的参数,并利用MATLAB 语言结合具体实例方便而快速地实现了该控制器的计算机仿真. 仿真结果表明:该控制方法提高了控制系统的动、静态特性,使系统获得了较好的性能.(The PID control and fuzzy control of the simplicity, flexibility and robustness of the integration, construction of a parameter self-tuning fuzzy PID controller. Through the fuzzy control rules online adjust the parameters of PID controller, and use specific examples of MATLAB language and quickly realize the convenience of the controller)

在MATLAB环境下实现了CDMA通信系统仿真，程序流程为：随机序列产生--WALSH码扩频--BPSK调制--加入（和不加入）高斯白噪声--BPSK解调--WALSH码解扩，对过程波形进行了存储，对加噪与不加噪情况下的解码结果进行了对比，并绘制出信噪比与误码率关系图。(In the MATLAB environment to achieve a CDMA communication system simulation, the program flow as follows: random sequence generated- WALSH yards Spread Spectrum- BPSK modulation- to join (and not to join) Gaussian white noise- BPSK demodulator- WALSH yards Solution expansion of the process of waveform storage, to add noise and without noise cases, the decoding results were compared, and draw out the signal to noise ratio and bit error rate diagram.)

计算输液管道频率的传递矩阵法,主要是计算RPV系统中的单跨输液管道。(the TMM of liquid-filled pipe)

利用matlab仿真雷达直射波与地面反射波干涉的雷达方向图。（仰角的大小对雷达作用距离的大小的影响）(Using matlab simulation radar direct wave direction of reflection wave interference with the ground radar chart. (the size of the size of the elevation of the radar range))

利用数学形态学开闭设计滤波器消除漂移信号(Opening and closing design using mathematical morphology filter to eliminate signal drift)

关于matlab的使用技巧,可为进一步提高matlab编程技术提供帮助.(With regard to the use of matlab techniques can further enhance the matlab programming techniques to help.)
