Well-posedness and exponential stability of solutions for piezoelectric beams under magnetic, delay and thermodiffusion effects

In this paper, we investigate the well-posedness and the asymptotic behavior of solutions to piezoelectric beams under magnetic, delay, and thermodiffusion effects. First, we establish the existence and uniqueness of solutions by applying semigroup theory. Then, using a perturbed...

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...
