Adaptive PI Control of Dynamic Voltage Restorer Using Fuzzy Logic
TLDR
The simulation result s have proved that the proposed adaptive PI controller greatly imp roves the performance of the DVR compared to the conventional PI controller.Abstract:
PI controller is very common in the control of DVR s. However, one disadvantage of this conventional controller is the fact that by using f ixed gains, the controller may not provide the requ ired control performance, when there are variations in t he system parameters or operating conditions. To overcome this problem, an adaptive PI controller us ing fuzzy logic is proposed. The controller is composed of fuzzy controller and PI controller. Acc ording to the error and error rate of the control system and fuzzy control rules, the fuzzy controlle r can online adjust the two parameters of the PI controller in order to be adapted to any variations in the operating conditions. The simulation result s have proved that the proposed control method greatly imp roves the performance of the DVR compared to the conventional PI controller.read more
