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...
For the problem of poor control precision of high-speed solenoid valves which are widely used in aero-engine control systems, a fuzzy-PID control system based on Soc single-chip is designed in this paper by using fuzzy self-tuning of PID parameters control algorithm. Because the Soc single-chip can control the output flow of high-speed solenoid valve very well by its PWM function, the monitoring system...
In this paper, the exoskeleton robot is first briefly introduced, the mathematical model for the upper limb exoskeleton robot and the force and position double-closed-loop control system are discussed. Then the authors discuss the type design of all sectors for the control system, and the various components of the system are given. Lastly, through the use of Matlab's Simulink software, the simulation...
Electroencephalography (simply called EEG) is a very useful bio-electrical signal applied in many research fields so that its measurement technology will develop very fast. For the EEG signal applied in the control of the robot hand, the basic characteristics of the EEG signal are analyzed in this paper. And then, a sampling circuit of EEG signal based on AT89C2051 single-chip is designed in detail,...
A BLDCM's PID controller and its system simulation are investigated in this paper. At first, the mathematics model of the motor control system is established, so that the system simulation is carried out respectively. And then, a PID controller is used to control the speeds between the two BLDCM, and the sine wave and triangle wave are selected to validate the effect of simulation. Finally, through...
