| 中文摘要: |
| 针对工业生产中永磁同步电机控制系统需降低生产成本、节约能源的实际需求,设计了永磁同步电机无测速传感器控制系统。选用矢量控制,保证电流与转矩成正比关系变化。利用Sigmoid函数代替切换函数,减小抖振。通过对不同负载情况下的仿真,验证了电机转速能较好地跟踪转速的给定值,滑模观测器估算精度较高,系统具有鲁棒性。 |
| 英文摘要: |
| To satisfy the actual demands of low cost and energy consumption in the industrial production of PMSM control devices, the authors of this paper have designed a PMSM sensorless control system, in which vector control is applied to ensure that the current and torque is proportional and Sigmoid function is used to replace the switching function to reduce chattering. The simulation of different loads showed that the motor speed could track the given value of the speed, and the estimation precision of the sliding mode observer was high, and the system was robust. |
