Abstract :
In this paper, a robust proportional-integral-derivative (PID) feedback compensator is designed for a low power radio-frequency (RF) amplifier, using Kharitonov´s theorem. The robust D-stability concept is used to achieve robust performance by clustering the characteristic polynomial equation roots of the closed loop system in a specified angular region. Then, the controller is realized and the obtained results demonstrate a desirable amplification over the operating frequency band. It is shown that the designed feedback compensator guarantees the robust stability and robust performance for a wide range parameter variation.
