An Optimal Nonlinear Controller Design on Multilevel Boost Converter Using Reinforcement Learning

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
Multilevel DC‐DC boost converters are critical in renewable and electric vehicle applications but face stability issues under constant power loads. This study introduces a modified integral nonlinear terminal sliding mode controller (MINTSMC) optimized with deep deterministic policy gradient (DDPG) within a digital twin framework, validated on hardware‐

Experimental Verification of the Performance of a Nonlinear Regulator Based on Genetic Algorithms in Improving the Power Quality of DFIG

International Transactions on Electrical Energy Systems, Volume 2026, Issue 1, 2026.
This experimental work investigates the energy control of the doubly fed induction generator. The energy control is performed using a direct power control based on a fractional‐order proportional‐integral (FOPI) regulator. The PI regulator parameters are calculated using a genetic algorithm. The use of this strategy ensures stable operation of the DFIG,
