Steam condensers in power plants are crucial for improving the efficiency of generation cycle by condensing and recycling steam from turbine. We used fractional-order proportional-integral-derivative (FOPID) controller to regulate pressure inside condenser system. adopted sinh-cosh optimizer (SCHO) tune this controller. analyzed fluctuations transient responses verify system balance between different operational states. Several well-known algorithms, including gravitational search algorithm, whale optimization manta ray foraging aquila optimizer, tested against SCHO. The simulation demonstrates that SCHO-based method outperforms other approaches terms integral time-weighted absolute error (ITAE), normalized overshoot, settling time. FOPID attained a minimal 14.80 ITAE, minimum percentage overshoot 6.06%, shortest time 17.66 s. stated values confirm offers superior more consistent performance under study.
