MSTMM‐Validated Machining Efficiency and Surface Roughness Improvement Using Evolutionary Optimization Algorithm

International Journal of Mechanical System Dynamics, Volume 5, Issue 2, Page 354-371, June 2025.
ABSTRACT Ultra‐precision machining (UPM) has been extensively employed for the production of high‐end precision components. The process is highly precise, and the associated cost of production is also high. Optimization of machining parameters in UPM can significantly improve machining efficiency and surface roughness. This study proposes an innovative

An Optimised Adaptive Integral Sliding Mode Control Approach for Multi‐Area Power Systems: Enhancing LFC Robustness and Stability With RES Integration and Time‐Delay Mitigation

IET Energy Systems Integration, Volume 7, Issue 1, January/December 2025.
ABSTRACT Frequency stability is vital to power system operation, especially in interconnected power systems (IPS) and smart grids where renewable energy sources and load fluctuations introduce unpredictability. This variability and time delay from decentralised control configurations can impair load frequency control (LFC) and compromise system ...
