A fractional-order PID (FOPID) controller induction motor driver with Y-source inverter is presented as a low-cost, minimized-component solution. This topology combines the advantages of the traditional 3-phase 4-switch inverter with those of the Y-source network. Besides its self-amplification properties, this topology has fewer switches and can also act as a buck converter. The FOPID controller contains five important variable coefficients. They are called proportional operator (Kp), integral operator (Ki), differential operator (Kd), integral operator (Ki), differential operator (Kd), fractional integral operator (λ) and fractional derivative (μ). The performance of the controller mainly depends on the chosen values of the above operators (Kp, Ki, Kd, λ, μ). One of the main goals of this article is to optimize the values of these five parameters to improve system performance. A new integrated Y-source inverter system enables drive-thru during voltage sags, reducing grid harmonics and extending the output voltage range. These new capabilities are demonstrated through analysis, simulation and experimentation
