【摘要】：基于永磁同步電機(jī)(PMSM)在旋轉(zhuǎn)坐標(biāo)系下的數(shù)學(xué)模型,選擇d軸電流增量和q軸電流增量構(gòu)成狀態(tài)變量,推導(dǎo)了交流永磁同步電機(jī)的增量式狀態(tài)方程,對模型預(yù)測控制(MPC)用于永磁同步電機(jī)的電流控制進(jìn)行了研究,提出了表貼式永磁同步電機(jī)(SPMSM)的模型預(yù)測電流控制算法,實現(xiàn)了對電流的前饋和反饋控制,可消除d軸和q軸電流的非線性耦合(運動耦合),改善電流控制的動態(tài)性能。仿真和實驗結(jié)果表明,相比PI調(diào)節(jié)器電流控制,模型預(yù)測電流控制器具有更好的去耦合效果和更快的動態(tài)響應(yīng)。
[Abstract]:Based on the mathematical model of permanent magnet synchronous motor (PMSM) in rotating coordinate system, the incremental state equation of AC permanent magnet synchronous motor is derived by selecting the increment of d axis current and Q axis current increment. The current control of permanent magnet synchronous motor (PMSM) using model predictive control (MPC) is studied. The model predictive current control algorithm of SPMSM is proposed. The feedforward and feedback control of current is realized. The nonlinear coupling between d axis and Q axis current can be eliminated, and the dynamic performance of current control can be improved. The model predicts that the current controller has better decoupling effect and faster dynamic response.
