| 中文摘要 |
| 针对传统整数阶滑模控制系统中存在的抖震问题, 本文提出了分数阶滑模控制策略并应用到永磁同步电机的速度控制. 传统滑模控制器中的开关函数由作用在切换流型或其整数阶导数面推广到其分数阶导数面, 利用分数阶系统的特性, 缓慢地传递系统的能量, 有效地削减抖震. 本文采用模糊逻辑推理算法, 实现软开关切换增益的自整定. 仿真和实验证明, 本文提出的分数阶滑模控制系统不但能有效地削减抖震, 而且能保持滑模控制器对系统参数变化和外部扰动的鲁棒性. |
| 英文摘要 |
| To deal with the chattering phenomenon existing in conventional integral order sliding-mode controller, we proposed a fractional order sliding-mode controller and apply to control the permanent magnet synchronous motor (PMSM). The soft-switching will not directly act on the sliding-mode surface or on its integral order derivative, but on its fractional order derivative. According to the property of fractional calculus, this action will reduce the chattering. Moreover, the fuzzy logic inference algorithm is used to obtain the gain of soft-switching. Simulations and experiments show that the proposed fractional order sliding-mode controller not only achieves better control performance than the conventional integral slidingmode control systems, but is also robust with regard to system parameter variations and external disturbances. |
