DC Motor Speed Control Part II: PID Feedback

From our previous article DC Motor Speed Control Part I: Open-loop Command, an experimental setup for DC motor is constructed and tested. The result shows that the command and actual motor speed differ significantly. Not a surprise. An open-loop control … Continue reading

DC Motor Speed Control Part I: Open-Loop Command

In this article, we discuss speed control of a simple brushed DC motor with incremental encoder feedback. A standard PID algorithm is implemented on PIC24EP256MC202, a 70 MIPS microcontroller from Microchip. We focus on constructing an experimental platform using a … Continue reading
