Elastic Robot Joints
Advanced Modeling and Control

This book focuses on the modeling and control of elastic robot joints for which each axis of the robotic manipulator is controlled as a single-input-single-output (SISO) system with disturbances, otherwise known as independent joint control. It also shows how to account for joint elasticities in a centralized controller when treating the robotic manipulator as a coupled multiple-input-multiple-output (MIMO) system. The book analyzes modeling and control solutions, supported by specially elaborated simulation examples and an experimental case study.
