| Abstract: | 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. |
