| Abstract: | The mathematic model of DC motor control system of a insulin pump was established.Furthermore,with PWM and PLL,the angular displacement of the motor could be precisely controlled;thereby the speed of the motor could be controlled.The simulation study was also performed.By phase-locked loop system response of frequency domain and time domain,the best phase-locked loop algorithm was obtained,thus the effectiveness and feasibility of the system was proved. |
