为了实现永磁同步直线电机的无位置传感器运行,以采样得到的电机三相电压和电流信号为输入信号,利用TM S320F2812 DSP,计算出电机动子的位置信号,作为控制系统的反馈信号。在DSP硬件功能和电机动子位置估算方法的基础上,完成了系统的硬件架构设计和软件流程设计。
For realizing the movement of Permanent Magnet Synchronous Linear Motor (PMSLM) without position sensor, take the motor's three-phase voltage and current as the input signals and use TMS320F2812 DSP to calculate the mover' s position of PMSLM, which is regarded as the feedback signal of control system. On the basis of hardware functions of DSP and the method of calculating the mover' s position of PMSLM ,the design of system hardware frame and software flow is completed.
