摘要
在分析建立永磁直线同步电机(PMLSM)的d-q轴动态数学模型的基础之上,提出了采用三环控制结构的永磁直线同步电机位置伺服系统,该伺服系统采用模糊PID控制方法。重点针对位置环的模糊PID控制器进行了分析设计,并利用MATLAB/Simulink进行了系统仿真。通过与传统PID控制器的仿真比较表明,所设计的模糊PID控制器能够显著提高位置伺服系统的动态响应性能。
Based on the analysis of dynamic equation of permanent magnet linear synchronous motors （PMLSM）, a position servo system of the permanent magnet linear motors with three-loop structure is proposed. This servo system employs fuzzy PID control. Furthemore, the fuzzy PID controller of the position loop is analysed and designed. The MATLAB simulation results show that the fuzzy PID controller promotes the dynamic performance of servo system comparing to theconventional PID controller.
