Control of Velocity-Constrained Stepper Motor-Driven Hilare Robot for Waypoint Navigation
Engineering, 2018 Finding an optimal trajectory from an initial point to a final point through closely packed obstacles, and controlling a Hilare robot through this trajectory, are challenging tasks. To serve this purpose, path planners and trajectory-tracking controllers

Communication-aware trajectory tracking
2008 IEEE International Conference on Robotics and Automation, 2008 This paper investigates the scenario of a robot making a tradeoff between tracking a time-varying reference trajectory and stopping to communicate at points where the radio signal strength is high. Under the assumption that the signal is subject to multipath fading, we formulate this as a hybrid optimal control problem with penalties on tracking error,

Safe Trajectory Tracking in Uncertain Environments
IEEE Transactions on Automatic Control, 2022 In Model Predictive Control (MPC) formulations of trajectory tracking problems, infeasible reference trajectories and a-priori unknown constraints can lead to cumbersome designs, aggressive tracking, and loss of recursive feasibility. This is the case, for example, in trajectory tracking applications for mobile systems in the presence of constraints ...
