A Fractional-Order Control Approach to Ramp Tracking with Memory-Efficient Implementation
(Chapter, 2020)We investigate the fractional-order (FO) control of arbitrary order LTI systems. We show that, for ramp tracking or input disturbance rejection, it is advantageous to include an FO integrator to the open-loop if we have ... -
Parameter Identification of Fractional-Order LTI Systems using Modulating Functions with Memory Reduction
(Chapter, 2021)The parameter estimation problem of a linear time-invariant fractional-order system is investigated by means of the modulating function method. Based on the assumption of known model structure and derivative orders, the ... -
A Trajectory-Driven SIMO mm-Wave Channel Model for a Moving Point Scatterer
(Chapter, 2021)In this paper, we propose a trajectory-based three-dimensional (3D) non-stationary channel model for a millimeter wave (mm-Wave) single-input multiple-output (SIMO) system. The proposed channel model is designed to capture ... -
Voltage Source Multilevel Inverters with Reduced Device Count: Topological Review and Novel Comparative Factors
