摘要:

研究了基于三相逆变器相电压占空比的简化的连续控制集模型预测电流控制。通过改进电压矢量的合成方式,保持和传统矢量控制方法相同控制性能的前提下,将电流预测计算的次数由6次减少为3次,同时提高了母线电压利用率。通过对比实验对该方法进行验证,结果证明该方法能获得和SVPWM控制相同的稳态性能,有效地降低了电流纹波,且保留了模型预测控制在动态过程的控制性能。

Abstract:

A simplified continuous control set model predictive current control (SCCS-MPCC) based on phase voltage duty cycle of three-phase inverter was studied. By improving the synthesis method of voltage vector and maintaining the same control performance as the traditional vector control method, the frequency of current prediction calculation was reduced from six times to three times, and the utilization ratio of bus voltage was improved. The scheme was verified through comparative experiments. The experiment results prove that the scheme can achieve the same steady-state performance as SVPWM control, effectively reduce the current ripple, and retain the control performance of the model predictive control in the dynamic process.

Key words: permanent magnet synchronous motor (PMSM), model predictive control (MPC), vector synthesis, principle of area equivalence
