[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.
