Neuro-fuzzy controller for enhancing the performance of extinction angle control of inverters in a MTDC-AC system

Constant extinction angle control of an inverter in a MTDC-AC system is of utmost importance for proper operation under all contingencies. In this paper, the process of control is treated as a pattern recognition problem. A neuro-fuzzy controller is implemented and used for online operation of a MTDC-AC system to enhance the performance of extinction angle control. The proposed controller has significantly improved the system performance for cases studied. >
