摘　　要：为提高同步电机励磁调节器的响应速度及鲁棒性,提出一种基于粒子群优化方法的同步电机分数阶鲁棒励磁控制器的设计方法。将同步电机的励磁系统进行线性化处理,使用分数阶系统理论推导了同步电机励磁调节器的分数阶传递函数模型;将分数阶系统进行加权,形成相应的增广系统,并提出了相关控制系统的鲁棒性能指标;在此基础上使用粒子群优化算法对分数阶PIλDμ控制器的参数进行优化整定,得出了结果。经实验验证,与使用传统传递函数模型及常规PID励磁调节器相比,所提出的控制方法响应速度明显提高,且具有较强的鲁棒性。To enhance the robustness and response speed of the synchronous machine excitate regulator,it was proposed a design method for robust fractional order PID （portional integral differential） control system,which was based on particle swarm optimization. The mathematic model of synchronous machine excitation system was linealized. The model came into realized,and the fractional order transform function had been got by using the theory of fractional order system. Then,the expanded system was formed according to weighting method. At the same time,it was presented robust evaluation of the system. Therefore,the particle swarm optimization had been applied to optimize the parameter of the fractional order PID controller. The results of experiment was given,which was based on the theory analysis. Compared with the traditional mathematic model of the excitate regulator and common PID controller,the response speed of proposed method has been improved,and has stronger robustness.
