| 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.

| Abstract: | 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 these motor control algorithms and it is important to implementation. 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 torque angle,flux linkage,power angle limiting and monotonicity of the system. A theoretical analysis is verified with the simulation,and the similarities and differences of stable operation of the two control algorithms are contrastively analyzed. |
