Beschreibung
Zusammenfassung:	The invention discloses a control system for LRA, applicable to an LRA having a speed sensing coil. The control system comprises a signal amplifier, an excitation device, a flow controller, a processing unit, and a driver. The processing unit is connected to the signal amplifier, the excitation device and the flow controller, so as to stop output, output the excitation signal as a driving signal or process the induction signal from the signal amplifier into an appropriate system damping coefficient and output as a driving signal when the flow controller outputs a stop, excitation or braking state signal, respectively.
