摘要

本文采用粒子群优化(PSO)技术寻找PWM交/交稳压器中选择性谐波消除问题的最优解。对于这类电压控制器，SHE导致非线性和超越方程;因此，用传统的数值方法求解这些问题，很大程度上取决于初始值的选择。提出的基于粒子群算法有效地计算所需的开关实例，以消除输出电压中预先指定的谐波。给出了消除不同谐波集的问题表述、目标函数和得到的开关角轨迹。利用Matlab/Simulink对理论结果进行了仿真验证。

Application of PSO for selective harmonic elimination in a PWM AC/AC voltage regulator

In this paper the particle swarm optimization (PSO) technique is used to find an optimal solution for the selective harmonic elimination (SHE) problem in PWM AC/AC voltage regulators. For this kind of voltage controllers, SHE leads to nonlinear and transcendental equations; as a result, solving them by conventional numerical methods highly depends on proper selection of initial values. The proposed PSO based algorithm affectively computes the required switching instances to eliminate pre-specified harmonics from the output voltage. Problem formulation, objective function and obtained switching angels trajectories for eliminating different sets of harmonics are presented. Simulation results using Matlab/Simulink are presented to confirm the theoretical results.
