摘要:
The present disclosure discloses a tactile vibration control system and method for a smart terminal. The system comprises: a command generator, a tactile driver, a linear resonant actuator, a sensing module, a feedback unit and a comparator; by arranging a plurality of sensors that can monitor or sense the vibrating status of the linear resonant actuator, multiple channels of the sensor signals are generated when the actuator vibrates; the feedback unit sends the sensing signals characterizing the physical quantities related to the vibration modes output by the plurality of sensors to the comparator as the feedback signal; and the comparator generates an error signal according to the feedback signal and a desired signal in the input signal and sends the error signal to the command generator so that the command generator adjust the generated initial commanding signal according to the error signal and achieves the close-loop control of the linear resonant actuator. The present disclosure can robustly estimate the status of the actuator and provide control, solve the phenomenon of residual trailing occurring when the linear resonant actuator vibrates, and achieve the technical effect of adjusting the vibrating status of the actuator in real time.
