| Abstract: | In accordance with the pulse characteristic of the load of the running-rigs which are driven by DC motor with small power,a dedicated digital speed-controlling unit for the electric running-rigs is developed using P87LPC768 MPU.The unit makes full use of MPU resources and FUZZY-PID algorithm,and it generates PWM pulse by automatically adjusting PID parameters in order to realize the speed control of the running-rigs.The results of industrial tests show that the unit has not only simple structure and high performance-to-price ratio but also high control precision to the speed of the running-rigs.And it can also be applied to the speed control of other sport-rigs. |
