摘要： 针对直流调速系统,设计了一种模糊自整定的分数阶内模控制器。首先将分数阶理论与内模控制(internal model control, IMC)相结合设计分数阶内模控制器,其参数可根据系统的相角裕度和穿越频率进行解析整定;然后在分析了相角裕度和穿越频率对系统性能影响的基础上,设计出模糊控制器,实现了系统根据转速偏差和偏差变化对控制器参数的在线自整定,克服了系统性能对相角裕度和穿越频率选择的依赖。仿真和试验结果表明模糊自整定分数阶内模控制器可使系统具有良好的动态响应、干扰抑制特性以及克服参数摄动的鲁棒性。

Abstract: A fuzzy self-tuning fractional internal model controller was proposed for DC speed regulation system. Firstly, the theory of fractional calculus and internal model control (IMC) were combined to design a fractional internal model controller, and the parameters of controller could be tuned according to the phase margin and crossover frequency of the system. Then, based on analysis of the impact of the phase margin and crossover frequency on the system performance, the fuzzy controller was designed. So, the online self-tuning of the controller parameters was realized according to speed error and its change, and the system performance dependence on the phase margin and crossover frequency selection was overcome. The simulation and experimental results showed that the proposed controller could make the system have a better dynamic response characters, disturbance rejection performance and robustness against parameters perturbation of system.

Key words: fractional order control, fuzzy control, DC speed regulating system, internal model control, phase margin, crossover frequency
