摘要:
针对永磁同步电机( PMSM )的三相逆变器死区时间导致转矩脉动增大的问题,提出了一种死区自适应补偿控制策略,通过给定电压积分计算的转子磁链和实际的磁链常数进行比较得到差值,自适应调节系统输出以减小差值,从而减小死区时间带来的影响。然后进行仿真验证,在 Simulink 中建立 PMSM 的磁场定向矢量控制( FOC )仿真模型,添加死区自适应补偿模块,得到在不同转速下的死区补偿优化前后的测试结果。仿真测试结果表明,所提的死区补偿策略能够有效优化电流波形并减小 PMSM 的扭矩脉动。
Abstract:
To address the issue of increased torque ripple in three-phase inverters of permanet magnet synchronous motors ( PMSM ) caused by dead-time , this study proposes a dead zone adaptive compensation control strategy.The strategy calculates the rotor magnetic linkage from the given voltage integral and compares it with the actual magnetic constant to determine the difference.The system output is then adaptively adjusted to minimize this difference , thereby reducing the effects of dead time.Simulation verification was conducted by establishing a field oriented vector control ( FOC ) simulation model of PMSM in Simulink , with a dead zone adaptive compensation module added.The study obtained test results of dead zone compensation optimization before and after at different speeds.The simulation test results demonstrate that the proposed dead zone compensation strategy can effectively optimize the current waveform and reduce the torque ripple of PMSM.
