【Abstract】 For realizing the movement of Permanent Magnet Synchronous Linear Motor (PM SLM) without position sensor, take the motor’s three-phase voltage and current as the input signals and use TM S320F2812 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.更多还原
