【摘要】:將基于平坦控制(FBC)運用到永磁同步電機(PMSM)電流環(huán)控制器的設計中,來提高電流環(huán)的動態(tài)性能。簡單介紹微分平坦系統(tǒng)的理論和平坦控制的架構,證明電流環(huán)平坦性;然后設計了基于FBC電流環(huán)控制器,包括前饋控制量的產(chǎn)生和誤差反饋補償,根據(jù)系統(tǒng)期望輸出量在空間規(guī)劃狀態(tài)變量的前饋控制量,用PI控制器產(chǎn)生消除的誤差反饋量,且前饋控制量在控制系統(tǒng)中處于主導地位從而提高電流環(huán)的動態(tài)性能,并推導出電流環(huán)的閉環(huán)傳遞函數(shù);搭建仿真模型,驗證控制算法的有效性。
[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.
