从频域上建立宽带阵列接收信号的模型，引出了2种宽带阵列信号处理的研究方法：非相干信号的处理方法（ISM）和相干信号子空间算法（CSM）。并利用MATLAB仿真软件,模拟远场、等功率、平稳的第三代移动通信手机信号，对2种算法性能进行对比。仿真结果表明，CSM算法相对ISM算法虽然加大了运算复杂度，但是能够更有效分辨出宽带相干信号。

分析了三相并联型有源电力滤波器(APF)原理和电流控制数学模型。接着将重复控制器嵌入到有源电力滤波器(APF)中，实现PI控制和重复控制的双闭环电流控制。同时讨论了重复控制的稳定性和稳态误差，分析了重复控制器的参数设计。最后在一台20 kVA并联型有源电力滤波器样机上验证了该方法的使用性和有效性。

为保证数字图像在传输过程中的安全问题,通过分析传统的基于高维混沌系统的图像加密算法,提出了一种图像加密改进算法。将位置置乱和像素替换加入到每次迭代中,并使加密数据流与明文信息相关,弥补了传统算法在应用中的漏洞和不足。理论分析和仿真实验表明,该算法具有良好的保密性和加密效果,密文对明文或初始密钥的任何微小变化具有强烈敏感性,相邻像素满足零相关性,具有较强的安全性和可操作性。
