摘　　要：目前永磁同步电机的主流控制方式主要有直接转矩控制和矢量控制,而系统能否稳定运行是这些电机控制算法的基础.分别基于两种控制算法的基本原理,从实际运行工作点出发,结合转矩角、磁链、电流角限幅和系统的单调性等理论,分析了永磁同步电机直接转矩控制和矢量控制的稳定运行区间,并运用仿真实验对理论分析进行了验证,对比分析了两种控制算法稳定运行规律的异同点.At present, the mainstream control methods of permanent magnet synchronous motor are direct torque control and field-oriented control. The stability is the basis of tliese motor control algoritlims and it is important to implementa-tion. In this paper, the stable operation range of permanent magnet synchronous motor direct torque control and permanent magnet synchronous motor field-oriented control is analyzed by combining the torquelimiting and monotonicity of the system. A theoretical analysis is verified with differences of stable operation of the two control algorithms are contrastivvly analyzed.
