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.
