Precise pressure control in shell-and-tube steam condensers is crucial for ensuring efficiency thermal power plants. However, traditional controllers (PI, PD, PID) struggle with nonlinearities and external disturbances, while classical tuning methods (Ziegler-Nichols, Cohen-Coon) fail to provide optimal parameter selection. These challenges lead slow response, high overshoot, poor steady-state performance. To address these limitations, this study proposes a cascaded PI-PDN strategy optimized using the electric eel foraging optimizer (EEFO). EEFO, inspired by prey-seeking behavior of eels, efficiently tunes controller parameters, improved stability precision. A comparative analysis against recent metaheuristic algorithms (SMA, GEO, KMA, QIO) demonstrates superior performance EEFO regulating condenser pressure. Additionally, validation documented studies (CSA-based FOPID, RIME-based GWO-based PI, GA-based PI) highlights its advantages over existing methods. Simulation results confirm that reduces settling time 22.7%, overshoot 78.7%, error three orders magnitude, ITAE 81.2% compared based The EEFO-based achieves faster convergence, enhanced robustness precise tracking, making it highly effective solution real-world applications. findings contribute optimization-based strategies plants open pathways further bio-inspired innovations.

The results demonstrate that CDWOA offers significant advantages in optimizing WTTs compared traditional algorithms. Particularly ultrahigh exhibits superior applicability. Furthermore, savings achieved increase with height. Finite element analysis indicates primary constraint governing convergence is fatigue strength, aligning well model's calculated results.
