Abstract

The paper will present a performance analysis of various types of controllers used in the Automatic Voltage Regulator (AVR) system. The AVR is a crucial component of power systems, responsible for regulating the voltage levels of generators to ensure a stable and reliable power supply. Different types of controllers, such as proportional integral derivative (PID), Z-N tuning, and LQR controllers, are evaluated and compared based on their performance metrics, including setting time, overshoot, and steady state error. Simulation findings show that each controller has its own strengths and weaknesses in terms of regulating voltage. Moreover, the selection of a controller is contingent upon the particular needs as well as the features of the power system. This analysis can provide valuable insights for engineers and researchers in selecting and designing appropriate controllers for AVR systems.
