Fault‐Specific Diagnostic Regions Based on Normalized DC Voltage and Current Indices for Photovoltaic Systems Using Routine Inverter and Environmental Data

Energy Science &Engineering, EarlyView.
This study proposes a fault diagnostic approach for photovoltaic systems using normalized DC voltage and current indices derived from routinely collected inverter and environmental data. The approach enables string‐ and array‐level fault diagnosis without additional measurement equipment and supports operation and maintenance decision‐making.

Production of recombinant human granulocyte‐macrophage colony‐stimulating factor in thermoinducible E. coli: Tuning inclusion body architecture and protein yield via dissolved oxygen control

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Recombinant protein expression in Escherichia coli frequently results in the formation of inclusion bodies (IBs), which provide high protein accumulation but often require additional steps to recover functional protein. Although culture conditions strongly influence IB physicochemical and structural characteristics, the impact of ...

The Pitch Control Algorithm of Wind Turbine Based on Fuzzy Control and PID Control

, 2013
Due to the special features of great inertia, pure lag and non-linearity provided with wind turbine, coupled with complex and variable working condition, it is difficult to achieve satisfactory control results simply by employing traditional PID, which ...

Characterization and Repetition Rate Locking of a 1 GHz Erbium‐Doped ZBLAN Waveguide‐Chip Comb Laser

Laser &Photonics Reviews, EarlyView.
A compact, erbium‐doped ZBLAN waveguide chip mode‐locked laser that self‐starts, delivers stable ultrashort pulses, and repetition rate locked to a 1 GHz radio‐frequency reference. The laser produces near transform‐limited 324 fs pulses and 12 nm bandwidth with low noise and long‐term stability, with potential applications in optical frequency ...

Inertial‐Based LQG Control: A New Look at Inverted‐Pendulum Stabilization

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Linear‐quadratic Gaussian (LQG) control is a well‐established method for optimal control through state estimation, particularly in stabilizing an inverted pendulum on a cart. In standard laboratory setups, sensor redundancy enables direct measurement of configuration variables using displacement sensors and rotary encoders. However, in outdoor
