摘　　要：针对传统煤矿电机工作效率低、控制精度差和成本高等问题,设计了一种矿用变频器无速度传感器矢量控制系统。该控制系统采用无速度传感器矢量控制算法实现电机变频器的控制,运用TI公司TMS320F28335型号的数字信号处理器作为系统的核心控制器。介绍了以功率单元、辅助电源和控制主电路组成的硬件电路,并对软件系统的架构和主中断程序进行了阐述。最后实验验证了该控制方案的可行性和有效性。Aiming at the problems of low work efficiencyent, poor control accuracy and higher cost for traditional coal mine motor, a speed sensofless vector control system for mine are designed. The control system adopts speed sensorless vector control algorithm to realize the control of the motor inverter and use digital signal processor of TMS320F28335 model of TI company as the core controller of the system. Introduces the hardware circuit composed of power unit, auxiliary power supply and control main circuit, and describes the structure of the software system and the main interrupt program. Finally, the feasibility and effectiveness of the proposed control scheme are verified by experiments.
