Development and analysis of adaptive PID controller using LMS algorithm for Distribution Generation-Inverter

The 90% controllers in Distribution generation are conventional PID controller. The selection of controller parameters is biggest challenge with change in system dynamics. In Distribution Generation, the Inverters are most common power electronics device used. It's output parameters are controlled with the help of controller. The Paper presents development of adaptive PID controller architecture based on adaptation of each controller parameter using Least Mean Square algorithm. The adaptive PID controller’s transient and frequency specifications are compared and verified with open system and classical PID controller response. The studied system is modeled, simulated and analyzed on MATLAB-SIMULINK environment. The result and analysis shows that adaptive algorithm can be used to tune and improve the flexibility of conventional PID controller
