Modulating Function‐Based Algebraic Observer for Conformable Fractional‐Order Systems

ABSTRACT We propose a finite‐horizon algebraic observer for conformable fractional‐order linear systems. The construction combines a conformable integration‐by‐parts identity with unitary modulating functions so that derivatives are transferred from noisy measurements to predesig...

Improving ADRC Strategy for DC-Link Voltage Regulation in PV Grid-Tied Four-Leg Inverters Using an Adaptive Nonlinear High-Gain Observer

In practical photovoltaic grid-tied four-leg inverter systems (PV-GTFLIs), changes in radiation, temperature, and grid voltage magnitude cause significant disturbances, including DC-link voltage disturbance and power unbalance, which can impact the system’s dynamic responses, con...
