摘要
介绍了永磁同步电机的直接转矩控制策略,在此基础上设计了一个基于DSP的电梯用永磁同步电机的直接转矩控制系统。该系统以SVPWM空间电压矢量控制技术为基础,以TI公司的TMS320LF2407A型DSP为核心处理器,能够对电机进行平稳调速和实时控制。给出了系统硬件和软件设计方案。
It presents the direct torque control plan of permanent magnet synchronous motor, and then designs a direct torque control system of permanent magnet synchronous motor in the elevator control based on DSP. The control system is based on SVPWM space volt- age vector control technology, by adopting TMS320LF2407A DSP of TI as control core. This system can control the permanent magnet synchronous motor smoothly in Real-Time. The article gives design methods of both the system hardware and software.
