About
Lotfi Chikh is a robotics researcher whose work lies at the intersection of mechanism design and advanced control theory, with a particular focus on parallel and cable-driven robotic systems. His research addresses the fundamental challenges of achieving precise, robust motion control in complex, nonlinear, and underactuated robotic platforms. Chikh’s most cited work, "Some investigations into the optimal dimensional synthesis of parallel robots" (27 citations), provides critical methodologies for designing parallel manipulators that maximize performance metrics like workspace and dexterity. He has made significant contributions to the control of Cable-Driven Parallel Robots (CDPRs), where his RISE feedback control approach (2020) tackles the formidable difficulties of cable flexibility, parameter variation, and actuation redundancy. Chikh has also advanced the field of soft and pneumatic actuation, developing robust cascade position-torque control strategies for Pneumatic Artificial Muscles (PAMs) and electropneumatic cylinders, combining predictive control with H∞ techniques to achieve high performance in parallel robotic applications. His work is characterized by a strong experimental focus, with real-time validation on testbeds, making his contributions directly applicable to industrial and research settings.
