摘　　要：通过对永磁同步电机驱动控制方法的研究,提出了一种新型的无差拍电流控制(dead beat current control,DBCC)策略。电机在高速或者需要高转矩响应时,为了减少转矩纹波,高带宽和高精度的控制电流环是必不可少的。无差拍电流控制是实现这些要求的首选之一。目前为止,国内外提出了多种无差拍电流控制方法。提出一种新型的考虑时间延时的DBCC方法,并且与传统的PI电流调节相比较,以进一步说明DBCC的优势。还提出了一种转子位置补偿的新算法,消除电机高速运行时的偏移误差。最后通过仿真和实验对该DBCC进行了验证。On the basic research for permanent magnet synchronous motor drives,a novel dead beat current control(DBCC)method was proposed.For reducing torque ripples in high performance drives,high bandwidth and accuracy of the current control loop are basic requisites especially at high speeds or when a fast torque response is required.A dead beat current control(DBCC)is one of the best candidates for these purpose.Various methods ofDBCC have been proposed and implemented.The performances of DBCC considering time delays were analyzed,and compared with a classical PI current regular to explain the DBCC′s advantage.A novel compensation method for the rotor position was also proposed to eliminate error coming up at high speeds.The assessment with simulation and experiment was used to verify the principle of DBCC in the end.
