About

Ritu Ranjan is a researcher specializing in the control and trajectory tracking of bipedal robotic systems, with a focus on nonlinear dynamics and robust control strategies. Their work addresses critical challenges in biped robot locomotion, including parameter uncertainties, unmodeled dynamics, joint friction, and external disturbances. In their most-cited paper, "PID and Backstepping Controller on a 2-Link Biped Robot" (2022, 3 citations), Ranjan compares classical PID control with backstepping control to handle nonlinearities and improve stability. A second notable contribution, "Trajectory Tracking of 3-link Biped Leg Robot using PD Controller and Robust Variable Structure Controller" (2022, 2 citations), develops mathematical models using Euler-Lagrange formulation and applies robust variable structure control (RVSC) for enhanced tracking performance. These works demonstrate Ranjan’s expertise in combining model-based design with robust control theory to advance biped robot locomotion. Though early in their career, Ranjan’s research lays important groundwork for more adaptive and resilient walking robots, with potential applications in prosthetics, exoskeletons, and humanoid robotics. Their focus on practical control solutions for complex robotic systems marks them as an emerging contributor to the field.
