Three phase stepping motor controller based on FPGA

为提高电机控制的精确度和灵活度,并减小其功耗与体积,用QuartusⅡ软件开发了一种基于FPGA的三相步进电机控制器。该电机控制器包括指定频率产生模块、频率调节模块、频率测量及LED显示模块、电机开关控制逻辑、电机运转方向控制逻辑等部分,整个系统使用VHDL硬件描述语言实现,采用全数字化控制。仿真结果表明,该控制器控制灵活、调速范围大、精度高、稳定性好。

In order to improve precision and flexiblity, reduce power consumption and volume of motor control, QuartusⅡ software was adopted to develop a three-phase stepping motor controller based on FPGA. The controller contains square wave generator module whose frequency could be assigned by users, frequency adjustor module, frequency measuring and LED display module, on-off module, and direction reverse module. Most of them were realized by VHDL and the whole system was totally digitalized. The simulation results show that the controller has the property of flexible control, wide speed range, high precision and stability.
