PIDD2 Controller Design Based on Internal Model Control Approach for a Non-Ideal DC-DC Boost Converter

In Today's world, the penetration of renewable energy sources in the modern power system for electrification of society and industry, is exponential growing. The dc-dc converter is the most important circuitry in such type of systems to regulate the output voltage. The boost converter is mostly preferred for step-up the output voltage level in practical applications. The output voltage regulation is a challenging task for control engineers of the boost converter. In this direction, the paper addresses a novel PID-Type controller for output voltage control of a non-ideal dc-dc boost converter. This novel PID-Type controller is a proportional-integral-derivative-double derivative (PIDD2) control design. Most important concern with the proposed control design is that a few tuning algorithms are available in the literature. In the paper, the tuning of PIDD2 is carried-out using internal model control (IMC) method. IMC is a robust tunning approach. The robustness of proposed control system is evaluated under the sudden change in load, sudden change in supply voltage, and sudden change in reference voltage. The efficacy of proposed control scheme is evaluated in comparison to the existing control schemes. The simulation results show the efficacy and effectiveness of the proposed controller design under the influence of different uncertainties and perturbations. Further, the experimental results present for the validation of proposed control design on nonideal dc-dc boost converter.
