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.}, title={Digital PID controllers with fractional variable order techniques and two discrete-time operator variants}, type={Article}, URL={http://czasopisma.pan.pl/Content/134106/PDF-MASTER/BPASTS-04719-EA.pdf}, doi={10.24425/bpasts.2025.153831}, keywords={fractional variable order operators, PID controllers, discrete-time, optimization}, }
