Abstract

This paper realizes the tactile and slip perception of prostheses finger by using of PVDF (Polyvinylidene Fluoride) piezoelectric membrane. The mathematics model of brushless DC motor is constructed and the characteristics of PVDF tactile and slipping sensor are analyzed. The PID controller is adaptive by designing the control system with tactile and slip feedback. The feedback system implements adaptive control. The simulink dynamic model of the control system is modeled. The simulation results show the control system can satisfy the requirements and has good response characteristics.
