Prescribed-time Closed-loop Performance Assessment: Comparative Case Study

Abstract

Control loop performance assessment is addressed in the context of the output feedback stabilization in fixed-time. Existing fixed- and prescribed-time output feedback control algorithms are reviewed and their pros and cons are discussed for performing the afore-mentioned task. The control performance assessment is based on integral indices. These indices are computed from the available data obtained from numerical simulations with a simple pendulum system affected by matched disturbances and measurement noise. Simulations results corroborates the pros and cons of the fixed-time output feedback algorithms in question.
