摘要
分析了音圈电机的工作原理,建立了音圈电机的数学模型,并对其传递函数进行数字化。在FPGA中,采用浮点数加法器和乘法器设计并实现了音圈电机仿真系统。测试了该仿真系统的冲击和阶跃响应,以及对常用电机驱动信号的响应情况。实验结果表明,该仿真系统误差低、调试方便、性能可靠。
The principle of voice coil motor is analyzed, and the mathematical model is built. The motor＇s transfer function is digitized. Floating-point adder and multiplier are used to design and implement the voice coil motor simulation system. The impulse response and step response of the system are detected. In addition, the response of a common signal to drive this motor is tested. The result of experiment shows that this simulation system has a low level of error and reliable performance.
