【Abstract】 Wavemeter requires that the guide can move in uniform motion and along straight line.The guide is driven by voice-coil motor that have simple structure,is easily maintained and rapidly responses.According to equivalent mechanical model and circuit model,the displacement-voltage transfer function of voice-coil motor.With PID regulator,the guide can move in steady speed state,which meet demands of the wavemeter.更多还原
