(Institute of Electrical and Electronics Engineers Inc., 2022) Celik, D.; Meral, M.E.; Waseem, M.
With the ever-increasing energy demand, the electric power sector and the energy industry are promoted to decentralization, decarbonization and digitalization. The digital platforms gradually become a megatrend for a clean energy system. Digitalization of the energy systems has conducted changes in various dimensions such as energy savings, sustainability and security. In this paper, the impact of digitalization on the electric energy systems, electric vehicles (EVs), sustainable development goal (SDGs) and greenhouse gas (GHG) emissions are analyzed and investigated. A systematic overview and discussions on the key drivers for digitalization and decentralization of energy systems are addressed. This paper provides significant insights for digitalization of the energy systems from a global perspective. Some enable, challenges and solutions are also handled to analyze the impact of digitalization. © 2022 IEEE.
Advancements in Nonlinear PID Controllers: A Comprehensive Review
(Elsevier Ltd, 2026) Çeli̇k, D.; Khosravi, N.; Khan, M.A.; Waseem, M.; Ahmed, H.
Proportional-integral-derivative (PID) controllers have been widely used in control engineering due to their simplicity, robustness, and effectiveness. However, traditional linear PID (L-PID) controllers face challenges in handling nonlinear dynamics, uncertainties, and varying operating conditions. To overcome these limitations, nonlinear PID (N-PID) controllers have emerged as a powerful alternative, offering improved adaptability, robustness, and transient response. Despite their increasing adoption, a comprehensive review of N-PID controllers, including their theoretical advancements, tuning methodologies, and applications, remains lacking. This paper provides an in-depth review of N-PID controllers, highlighting their advantages over L-PID controllers and their effectiveness in various engineering applications. It discusses the necessity of N-PID controllers, explores key advancements in their structural modifications, and analyses different tuning approaches, including adaptive, bio-inspired, and optimization-based methods. Additionally, the review covers their applications in process control, power converters, motor drives, and robotic manipulators, demonstrating their superior performance in handling complex dynamic systems. The paper concludes by identifying future research directions, emphasizing the potential of N-PID controllers in advancing control engineering by improving system stability, energy efficiency, and precision control. This review serves as a valuable resource for researchers and engineers seeking innovative control solutions for nonlinear and uncertain systems. © 2025 Elsevier Ltd.
