ABSTRACT Induction motors (IMs) are widely used in industry for their robustness and cost‐effectiveness, yet their nonlinear and multivariable dynamics pose significant challenges for high‐performance speed control. Model Predictive Control (MPC) is a well‐established solution but suffers from limitations related to model accuracy and parameter ...

Schematic diagram of the whale optimization algorithm (WOA)–optimized fuzzy proportional–integral–derivative (PID) controller. The WOA is employed to dynamically tune the scaling factor expressions and fuzzy control parameters (a(e)a(e), a(ec)a(ec), βpβp, βiβi), as well as the initial PID gains (kp0kp0, ki0ki0), based on the error (ee) and its ...

Targeting progressive multiple sclerosis: Toward mechanism‐informed precision medicine
Abstract Multiple sclerosis has undergone a therapeutic revolution over the past three decades. Randomized clinical trials and real‐world data demonstrate that modern disease‐modifying therapies substantially reduce relapse rates and acute inflammatory activity detected by magnetic resonance imaging (MRI).
