Homothetic Tube‐Based Adaptive MPC

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT This article presents a homothetic tube‐based adaptive model predictive control strategy to handle discrete‐time linear time‐invariant (LTI) systems with parametric uncertainties and hard constraints imposed on the states and the control inputs.

Energy‐Based Trajectory Tracking for Underactuated Mechanical Systems: Velocity‐Free and Disturbance Rejection Methods

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT This work investigates three energy‐shaping control approaches to address the trajectory‐tracking problem for specific classes of underactuated mechanical systems. In particular, the notions of contractive systems and dynamic extensions are utilized to solve the trajectory‐tracking problem while addressing implementation issues such as the ...

Real‐time Nonlinear Model Predictive Control of a Robotic Arm Using Spatial Operator Algebra Theory

Journal of Field Robotics, EarlyView.
ABSTRACT Nonlinear model predictive control (NMPC) has inherent challenges, such as high computational burden, nonconvex optimization, and the necessity of powerful and fast processors with large memory for real‐time robotics. In this study, a new NMPC strategy is proposed using Spatial Operator Algebra (SOA) theory to address these challenges, and ...
