本文研究了粒子群优化算法(PSO),在全三维粒子模拟(PIC)软件CHIPIC平台上,设计了PSO优化模块,成功研制了PIC/PSO代码.接着,研究了多频(包括单频)微波的输出功率特性,并根据该特性设计了一类目标函数.采用该类型优化目标函数,分别对单频与双频相对论返波管(RBWO)进行了模拟优化.模拟优化结果显示:随着优化过程的进行,单频RBWO的频率特性向单频靠近,双频RBWO的频率特性则向等幅双频靠近,它们的输出功率都逐渐增大.这表明通过控制该类型目标函数参数,该PIC/PSO代码可分别对单频与双频RBWO进行优化.
Particle swarm optimization algorithm (PSO) is studied in this paper, and the PSO optimization module is designed on the CHIPIC platform of full three-dimensional particle simulation (PIC) software, and the PIC / PSO code is successfully developed.Furthermore, And a class of objective function is designed according to this characteristic.With this type of optimization objective function, the RBWO of single-frequency and dual-frequency relativistic wave tube (RBWO) are simulated and optimized respectively.The simulation results show that with the optimization In the process, the frequency characteristics of the single-frequency RBWO approach the single frequency, and the frequency characteristics of the dual-frequency RBWO approach to the constant amplitude and dual frequency, and their output power increases gradually.This shows that by controlling the type of objective function parameters, the PIC The / PSO code is optimized for single and dual frequency RBWO respectively.
