提高电源的动态响应 非线性和复杂的系统是一个转换器 电力电子的有趣的挑战。摘要介绍了 设计和实现数字PID控制器使用 混沌粒子群优化(复)提振 转换器,提出了自动调优转换器的方法 最优启动响应。当系统启动时,处理器 单元分析了开环启动响应转炉和 在一些迭代使用复准备最佳反应 算法。使用逻辑映射混沌映射序列 增加它的收敛速度和精度。模拟 和实现结果显示提出的效率 方法(Improving dynamic response of DC-DC
converters which are nonlinear and complicate systems is an
interesting challenge in power electronics. This paper presents the
design and implementation of digital PID controller using the
chaotic particle swarm optimization (CPSO) for a Boost
converter and proposes an approach for auto tuning converter
optimum startup response. When the system starts, processor
unit analyses the open loop startup response of converter and
prepares optimum response during some iteration using CPSO
algorithm. Chaotic mapping using logistic map sequences
increases its convergence rate and resulting precision. Simulation
and Implementation results show efficiency of proposed
approach)

b)当平面波信号分别从0:1:180度方向入射时，指向90度的波束形成器的输出序列经过平方求和后的分贝数输出（把所有181个输出绘制在同一幅图中)(Assuming N=16, f=62.5, fs=1KHz, uniform weight, and the code gives:
a) 90 degree response when incidence angles are: 0: 10: 100 degrees
b) 90 degree spectral response when incidence angles are: 0:1:180 degrees )
