摘要
在PMSM的无位置和无速度传感器控制驱动方面,构建了一种基于滑模变结构理论的状态观测器,同时,针对传统的三相电流检测或母线电流检测方式中存在的不足,根据基尔霍夫定理,提出了一种更为经济简洁的相电流检测方法,应用于PMSM矢量控制系统中,能准确有效地估算出转子磁链位置角。最后,采用TMS320C24X验证了检测和控制方法的正确性。
At the sensorless control and drive aspect of permanent magnetism synchronous motor( PMSM), a new state estimation algorithm for sensorless control of PMSM was designed in this paper. At the same time, a simpler and more direct phase current check method was put forward to compensate for the deficiency existed in the three-phase current or the bus current check method. The application in PMSM vector control helped gain the exact and efficient estimation of rotor posi- tion. Experimental results based on TMS320C24X verifies the correctness of sensorless algorithm and current detecting.
