PID and Fractional Order PID Based Regulated Multiple Output Flyback Converter

The study centers on the design practice and application of a DC to DC Flyback Converter (FC) within a closed-loop system. DC to DC conversion, comprising six-sided decagon conversion, is a prominent area of research in power electronics engineering. In applications requiring varied output voltages from a single input, conventional single input single output DC to DC converters used in telecommunications and computers exhibit drawbacks such as inefficiency, low power density, and high system cost. To address these limitations and achieve high efficiency and power density, multi-output power converters are gaining traction. A Multiple Output Flyback Converter (MOFC) is specifically designed, modeled, and simulated using Simulink to regulate output voltage to desired levels despite varying loads and disturbances on the source side. Two control methods, Proportional Integral Derivative Control (PIDC) and Fractional Order PID Control (FOPIDC), are employed to generate gating pulses for the converter based on reference signals. Performance analysis involves evaluating constraints i.e. Time of Settling (TS), Time of Rise (TR), and Overshoot (OS). Comparative analysis of the control methods is conducted to assess their effectiveness in achieving desired outputs.
