An Enhanced Model of PID Controller Integrated with Dynamic Shifting Method for the Bi-Directional Converter

Abstract

In the DC-DC converter design and its characteristics, the major parameters that are basically considered are current flow in the circuit and controlling pulse generation for the switching devices to manage the reduction of noise rate comparing to references value.The overall functionality of the converter is depends on the controlling signal that are generated for the switching devices. Since, there are several methods that refers some static rules and its conditions to provide controlling pulses for gate controlled switches. To enhance the performance of DC-DC converter, this paper proposed a novel controlling method to regulate the DC power with reduced level of noise. This can be achieved by an optimal selection of parameter gain with respect to the feedback error signal using Dynamically Shifted Proportional Integral Derivative (DS-PID) controller. This can tune the parameters of controller to update the gain factor of the converter design which can manage the regulation factor. The arrangement of active components also filters the output waveform to regulate and boost up the DC power. This is simulated for the source of PV system and the performance analysis justify the efficiency of proposed work.
