摘要

摘要: 针对提出的直接驱动液压伺服泵新原理，设计了一种短行程永磁直流直线振荡电机，阐述了基于最小磁阻理论的电机工作原理，采用一种哈尔巴赫磁极阵列空心动子设计结构，用于提高电机动态响应能力，并利于谐振弹簧的安装.利用Matlab/Simulink建立了电机的集中参数数学模型并给出传递函数，通过正弦电压扫频激励，获取了电机空载下的电流频率特性以及恒定负载下的效率频率特性.基于电机模型设计了电流环与位置环双闭环控制结构，用于提高电流的频响与位置跟踪能力.最后对设计的电机进行了空载谐振与闭环动态实验研究，实验与分析仿真结果基本吻合，验证了电机模型与闭环控制结构的有效性.

Abstract: According to the proposed new principle of directly-driven hydraulic serve pump, a novel short stroke permanent magnet linear oscillating motor (LOM) was designed. The LOM working principle based on minimum reluctance rule was elaborated, and a special hollow mover design structure employing Halbach PMs array was adopted to improve the motor dynamic response ability and facilitate the installment of resonant springs. The lumped parameter mathematical model and transform function of LOM was established by Matlab/Simulink. Through sinusoidal voltage frequency sweep excitation, the LOM frequency characteristics of current with no load and of efficiency with constant load was acquired. According to the motor model, a dual-loop control structure with current loop and position loop was designed to improve the current frequency response and position tracking performance. Finally, the LOM experiments for unloaded resonance and dual-loop control strategy were carried out. The experimental results are coincided with the simulation results basically and verify the effectiveness of LOM model and control structure.
