Title:
TACTILE VIBRATION CONTROL SYSTEM AND METHOD FOR SMART TERMINAL
Document Type and Number:
WIPO Patent Application WO/2017/113651
Kind Code:
A1
Abstract:
Provided are a tactile vibration control system and method for a smart terminal. The system comprises: a command generator (11), a tactile driver (12), a linear resonant actuator (13), a sensing module (14), a feedback unit (15), and a comparator (16); the sensing module (14), which comprises a plurality of sensors, monitors or senses the state of the linear resonant actuator (13), thus when the linear resonant actuator (13) vibrates, it generates a multi-channel sensor signal (1, ..., N); the feedback unit (15) takes as a feedback signal, and sends to the comparator (16), the sensor signal (1, ..., N) of the physical quantity associated with the characteristic vibration mode outputted by the plurality of sensors; according to the feedback signal and the desired signal in the input signal, the comparator (16) generates an error signal and sends same to the command generator (11), causing the command generator (11) to adjust according to the error signal the original command signal, thus performing closed-loop control of the linear resonant actuator (13). The system is capable of robustly estimating the state of the linear resonant actuator (13) and controlling same; thus the residual phenomenon of trailing when the linear resonant actuator (13) is vibrating is resolved, and the state of vibration of the linear resonant actuator (13) is adjusted in real time.
