Description: 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 Platform: |

Description: ：针对传统矩阵变换器存在电压传输比低和输出性能易
受非正常输入影响的两个固有缺陷，提出一种Z–源双级矩
阵变换器(Z-source two-stage matrix converter，ZSTSMC)及
其调制方法。利用Z–源网络的升压特性以提高电压传输比，
通过Z–源网络电容电压闭环对直通因子进行自适应地调
节，从而有效抑制非正常输入对输出性能的影响。闭环控制
中采用一种非线性PID 算法，削弱了Z–源网络表现出的非
最小相位特性带来的不良影响，提高了系统动态性能和抗扰
能力。仿真和实验验证了该拓扑的可行性和正确性。-A novel Z-source two-stage matrix converter
(ZSTSMC) and its modulation strategy were proposed to
overcome two main drawbacks of conventional matrix
converters, i.e., low voltage transfer ratio and low immunity to
abnormal input voltages. The Boost voltage characteristics of
Z-source network was introduced to improve the voltage
transfer ratio. The shoot-through index was adaptively
controlled by Z-source capacitor voltage closed-loop, so as to
be immune to the disturbance of abnormal input voltages. The
nonlinear PID controller was employed to eliminate effects
caused by non-minimum-phase characteristic presented in
Z-source network and to improve the dynamic performance
and robustness of the system. Finally, the validity and
feasibility of this topology were verified by simulation and
experiment results. Platform: |
