About

Vikram Chopra is a control systems researcher whose work centers on the stabilization and robust control of underactuated, nonlinear dynamical systems—specifically inverted pendulums. His research bridges classical control theory with intelligent, adaptive techniques to solve benchmark problems in dynamics and control. Chopra’s major contributions include the development of an integral sliding mode controller for robust stabilization of spatial inverted pendulums, a method that effectively handles system nonlinearities and uncertainties. He has also pioneered the integration of Linear Quadratic Regulator (LQR) design with Adaptive Neuro-Fuzzy Inference Systems (ANFIS), creating hybrid controllers that combine optimal performance with learning-based adaptability. His most cited work, “Robust stabilization control of a spatial inverted pendulum using integral sliding mode controller” (2020), has garnered 13 citations, demonstrating its relevance to researchers working on real-world applications like segways, self-balancing robots, and VTOL aircraft. Through comparative studies of PID, ANFIS, and LQR-based controllers, Chopra has systematically advanced the understanding of how intelligent control can outperform traditional methods in stabilizing complex, unstable systems. His work provides foundational insights for students and engineers tackling modern control challenges.
