HERNANDEZ-ROSALES, C.; FEMAT, R.; RUIZ-VELAZQUEZ, E. e SOLIS-PERALES, G.. A standard microcontroller based Discrete-Time PI for controlling the motion of a DC-Gearmotor. J. appl. res. technol [online]. 2005, vol.3, n.1, pp.44-52. ISSN 2448-6736.
This paper shows how the INTEL© D8751 H microcontroller can be used to control the motion of a DC-Gearmotor. One advantage of this design is that does not require external memory RAM/EPROM to perform the control of the motor. A precision potentiometer and an analog-to-digital converter (ADC) are used to measure the motor angular position. The ADC is driven by the ALE signal from the microcontroller; therefore an external signal clock is not required. In order to implement a discrete-time PI controller and a discrete-time filter, specific libraries were designed. Moreover, other libraries based on micro C® compiler, has been modified. Finally, experimental results show a good performance of the embedded system.
