About

Dr. Savitha Ramasamy is a leading researcher in precision motion control for surgical robotics, with a particular focus on piezoelectric ultrasonic actuators (PUAs) and their application in delicate medical procedures. Her most cited work, "Non-singular Terminal Sliding Mode with Perturbation Viewer for Ear Surgery Robot" (2025, 5 citations), addresses critical challenges in controlling PUAs for the VTA surgical ear robot. Dr. Ramasamy's major contribution lies in developing a non-singular terminal sliding mode controller that effectively overcomes nonlinearities, uncertainties, and disturbances inherent in PUA systems, enabling unprecedented precision for microsurgery. This work has significant implications for improving outcomes in otologic surgery, where even micrometer-level errors can have serious consequences. Her research bridges the gap between advanced control theory and practical medical applications, demonstrating how robust sliding mode techniques can be adapted for real-time surgical environments. The perturbation viewer component of her controller provides real-time disturbance estimation, further enhancing system reliability. Dr. Ramasamy's innovative approach positions her at the forefront of surgical robotics control, with her work serving as a foundation for future developments in autonomous and semi-autonomous surgical systems.
