Fuzzy Self-Adaptive PID Control Based on BP Neural Network for TCSC

The flexible AC transmission system performance will be impacted directly by the controllers, therefore, the investigate in FACTS technology has been focus on the control system. With the characteristics and principles of the TCSC operation, this paper deals with the control of TCSC and a kind of fuzzy adaptive PID controller based on BP neural network is presented, which solved the problem in the linear of PID controller. The parameters of the controller are dynamically adjusted with the output of the BP neural network. So the control performance can be satisfied momentarily. The simulation results illustrate that the control strategy can be performed easily and have relatively high control precision.
