| 中文摘要 |
| 为了增强永磁同步电机(PMSM)伺服系统的抗干扰能力, 本文设计了一种基于最大转矩/电流(MTPA)原理 的自适应滑模控制器. 控制器根据MTPA控制方法确定定子直轴和交轴电流, 并利用滑模控制增强了系统的抗干扰 能力, 但同时给系统带来抖振. 为了削弱系统抖振, 设计了一种改进的自适应滑模趋近律用于位置控制. 为了增加 控制器的实用性, MTPA控制采用函数曲线拟合法. 仿真结果表明, 所提出的控制器有效增强了系统的动态性能、稳 态性能及鲁棒性, 并有效削弱了滑模控制带给系统的抖振. |
| 英文摘要 |
| In order to enhance the disturbance attenuation of the permanent magnet synchronous motor (PMSM) servo system, an adaptive sliding mode controller based on maximum torque per ampere (MTPA) control is designed in the paper. The MTPA control is used to obtain the d; q-axes currents, and the sliding mode control is used to enhance the disturbance attenuation of the system, but the chattering is also brought to the system. In addition, an improved adaptive sliding mode reaching law is designed for the position control to attenuate the chattering. Furthermore, the polynomial curve fitting method is adopted in the MTPA control which strengthens the practicability of the controller. The simulation results show that the proposed controller not only enhances system dynamic、static performances and robustness, but also attenuates the chattering caused by sliding mode control. |
