基于FPGA直流电机的PWM控制

FPGA-based PWM Control for DC Motors

应用PWM实现直流电机转速的控制,可用可编程序控制器PLC、单片机等方案来实现。但是这些控制方法的功能修改及调试都需要硬件电路的支持,在一定程度上增加了功能修改及系统调试的困难。因此,在设计中采用EDA技术,应用目前广泛应用的VHDL硬件电路描述语言,实现直流电机转向的控制设计,利用QuartusⅡ集成开发环境进行综合、仿真。仿真结果表明,应用VHDL硬件电路描述语言实现直流电机控制具有良好的控制效果。

For PWM DC motor speed control,one can use the programmable logic controller （PLC）,SCM,and other programs.However,modifying these functions and debuging control methods all need the support of hardware circuit.To a certain extent,it increases the difficulty of functional changes and system debugging.Therefore,this paper uses EDA technologies and hardware circuit description language VHDL which are now widely applied to complete the DC motor steering control.Quartus Ⅱ is used to integrate the development environment for synthesis,simulation.Simulation results show that the application description language VHDL is effective for hardware circuit DC motor control.
