Abstract
Aimed at the issues of deadbeat direct torque and flux control strategy(DB-DTFC)such as relying on the accurate motor model,high computational load,and coupling between torque and flux,a simplified strategy of DB-DTFC for permanent magnet synchronous motor which based on flux planning was proposed.Firstly,perform flux linkage planning for the permanent magnet synchronous motor across the full-speed-range within the stator field-oriented flux linkage coordinate system.Secondly,utilizing d-axis flux for decoupling torque and flux linkage,and a sliding mode torque controller was designed to construct a simplified strategy of DB-DTFC with small signal closed-loop.Finally,simulation and experimental results show that compared with the traditional DB-DTFC,the simplified DB-DTFC proposed has a shorter calculation time and is not sensitive to the change of motor inductance.At the same time,it has better flux and torque tracking performance.This strategy achieves high-performance motor control through the domestically developed 335 chip,demonstrating a viable pathway for implementing DB-DTFC methodology in cost-efficient hardware architectures.It provides critical technical validation for advancing industrial-grade motor control systems that balance premium performance with economic feasibility.关键词
