Neurocontroller based on ADHDP for rectifier in HVDC system

A novel neurocontroller based on ADHDP for rectifier in HVDC transmission system is presented in this paper. The action dependent heuristic dynamic programming (ADHDP), a member of the adaptive critic designs family is used for the design of the rectifier neurocontroller in HVDC. The action network and critic network of the neurocontroller are designed using BP artificial neural networks. Using a proportional-integrator approach, the proposed neurocontroller is capable of dealing with actual rather than deviation signals. Simulation results are provided to show that the proposed controller performs better than the conventional PID controller.
