About

Himanshu Chhabra is a control systems researcher whose work sits at the intersection of fractional order control, fuzzy logic, and intelligent robotics. His research focuses primarily on designing advanced controllers for nonlinear and coupled dynamic systems, with a particular emphasis on robotic manipulators. Chhabra has made significant contributions to the development of fractional order PID (FO-PID) and fuzzy PID architectures, pioneering hybrid frameworks that combine the mathematical precision of fractional calculus with the adaptability of artificial intelligence-based control strategies. Among his most influential works, his 2018 paper introducing a two-degree-of-freedom (2DOF) fractional order fuzzy PID controller has garnered 68 citations, reflecting strong community interest in expert control systems for nonlinear applications. His 2019 work on robust nonlinear fractional order fuzzy PD plus fuzzy I controllers, with 48 citations, further solidified his reputation in robust control design. A notable contribution is his NLF-PID framework, which incorporates nonlinear hyperbolic error functions cascaded with fractional order control for two-link rigid robots. His later work explores self-regulatory fractional fuzzy controllers using analytical, formula-based fuzzy logic, demonstrating a consistent drive toward more interpretable and practically deployable intelligent control solutions.
