摘要/Abstract

摘要： 提出一种新的模型预测控制策略,利用固定占空比合成新的电压矢量,在合成的过程中,不再使用零电压矢量,能够有效抑制共模电压;在电压矢量选择方面,进行两步预测,第一步是利用模型预测电流控制(MPCC)原理,进行扇区判断,在离散过程中采用龙格库塔的计算方式;在进行第二步预测时,为避免模型预测转矩控制中权重系数的问题,采用模型预测磁链控制(MPFC)的方法,选择最优电压矢量。仿真结果表明,系统不仅可以保持良好稳态性能,还能够有效抑制共模电压。

Abstract: A new model predictive control strategy was proposed. A new voltage vector was synthesized by using the fixed duty ratio, the zero vector was not used in the synthesis process, which could effectively suppress the common mode voltage. In terms of voltage vector selection, two steps of predictionwere carried out. The first step was to use the model predictive current control (MPCC) principle to judge the sector. Runge-Kutta calculation method was adopted in the discrete process. In the second step, model predictive flux control (MPFC) was used to select the optimal voltage vector in order to avoid the problem of weight coefficient in model predictive torque control. Simulation results show that the system can not only maintain good steady-state performance, but also effectively suppress common mode voltage.

Key words: permanent magnet synchronous motor(PMSM), model predictive current control(MPCC), model predictive flux control(MPFC), common mode voltage,Runge-Kutta method, sector judgment, dead-beat control
