 abstract={This paper introduces a control strategy utilizing the Fractional Variable Order PID digital controller (FVOPID). We employ two variants of fractional discrete-time operators with variable order: the Grünwald-Letnikov type and its convolution version. We examine and compare the performance of both controllers types on a higher order plant. Parameter optimization is conducted using a particle swarm algorithm.},
