Fractional Gradient-Based Model Reference Adaptive Control Applied on an Inverted Pendulum-Cart System Open
This study introduces a novel model reference adaptive control (MRAC) framework that incorporates fractional-order gradients (FGs) to regulate the displacement of an inverted pendulum-cart system. Fractional-order gradients have been shown…
