Abstract This paper introduces a nonlinear PI controller for improved speed regulation in permanent magnet direct current (PMDC) motor drive systems. The nonlinearity comes from the exponential (Exp) block placed front of classical controller, which uses tunable function to map error nonlinearly. Such configuration has not been studied till now, thus meriting further investigation. We consider an (EXP-PI) and attain best performance this its parameters are optimized offline using salp swarm...

As the transition to clean energy accelerates, wind plays a crucial role in power generation, particularly remote onshore and offshore locations. The integration of hybrid AC/DC networks with multi-terminal high-voltage direct current (MTHVDC) systems enhances transfer capability reliability. However, maintaining stable operation under both normal disturbed conditions remains challenging. This paper applies Flexible Universal Branch Model (FUBM) incorporating MTHVDC, providing unified...

In speed control systems, which is desirable that the of a controlled object should track reference as fast possible and at same time provide good robustness to load variations. As far conventional PI controllers are concerned, once their parameters tuned for solely one operating condition, they remain constant during whole operational cycle therefore, poor controller performance may arise unexpectedly when condition changed. To overcome this problem, incorporated by fuzzy logic (FLC)...
