Low-cost embedded solution for remote control of DC motors

Proportional Integral Derivative (PID) control is the most common control algorithm used in industry today. The popularity of PID controllers can be attributed to their effectiveness in a wide range of operating conditions, their functional simplicity and how easily engineers can implement them using up-to-date computer technology. This article discusses PID control and practical implementations using radio frequencies signals and provides a brief overview on tuning parameters of PID controllers.
