【摘要】：将基于平坦控制(FBC)运用到永磁同步电机(PMSM)电流环控制器的设计中,来提高电流环的动态性能。简单介绍微分平坦系统的理论和平坦控制的架构,证明电流环平坦性;然后设计了基于FBC电流环控制器,包括前馈控制量的产生和误差反馈补偿,根据系统期望输出量在空间规划状态变量的前馈控制量,用PI控制器产生消除的误差反馈量,且前馈控制量在控制系统中处于主导地位从而提高电流环的动态性能,并推导出电流环的闭环传递函数;搭建仿真模型,验证控制算法的有效性。
[Abstract]:In order to improve the dynamic performance of permanent magnet synchronous motor (PMSM), the flat control (FBC) is applied to the design of (PMSM) current loop controller. This paper briefly introduces the theory of differential flat system and the structure of flat control, proves the flatness of current loop, then designs a current loop controller based on FBC, which includes the generation of feedforward control quantity and error feedback compensation. According to the feedforward control of the desired output in the spatial planning state variable, the PI controller is used to generate the eliminated error feedback, and the feedforward control is dominant in the control system to improve the dynamic performance of the current loop. The closed-loop transfer function of the current loop is deduced and the simulation model is built to verify the effectiveness of the control algorithm.
