| 摘 要： | 为了提高直流调速系统性能,将直流调速系统速度控制器设计为分数阶PI(FOPI),并与整数阶PI控制特性进行比较。在确定FOPI/PI控制器参数时,根据不同目标函数用粒子群算法对控制器参数进行了优化,并分析了不同目标函数所确定的控制器参数对调速系统性能的影响。仿真表明:FOPI有较好的控制性能。在设计控制器参数时,可根据性能要求选用不同的目标函数优化设计控制器参数。

| Abstract: | In order to improve the performance of DC speed control system, the DC speed controller was designed as a fractional order PI (FOPI) and was compared with integer order PI for the control characteristics. When determining the FOPI/PI controller parameters, optimization was performed according to different objective functions using the particle swarm optimization algorithm. The influence of the controller parameters determined by different objective functions on the performance of the speed control system was analyzed. Simulation experiments showed that FOPI controller had better control performance. In the design of controller parameters, according to the performance requirements, different objective functions could be selected to optimize the design. |
