Trajectory control of flexible manipulators [PDF]
, 1998 We present some feedback control techniques recently developed for the exact solution of trajectory tracking problems for manipulators with flexible elements. Two classes are considered: i) robots with rigid links but with elastic transmissions, in which flexibility is concentrated at the joints, and ii) robots with lightweight and/or long arms, where ...

Self‐supervised vessel trajectory segmentation via learning spatio‐temporal semantics
IET Intelligent Transport SystemsThe study of vessel trajectories (VTs) holds significant benefits for marine route management and resource development. VT segmentation serves as a foundation for extracting vessel motion primitives and enables analysis of vessel manoeuvring habits and ...

Predictive Current Trajectory Control for PMSM at Voltage Limit
IEEE Access, 2020 This paper presents a fast predictive current trajectory strategy for permanent magnet synchronous motors (PMSMs) at voltage limit. The current hexagon obtained from the voltage hexagon of the inverter represents the region that the currents can reach in

Secure UAV Communication With Cooperative Jamming and Trajectory Control [PDF]
IEEE Communications Letters, 2018 This letter presents a new cooperative jamming approach to secure the unmanned aerial vehicle (UAV) communication by leveraging jamming from other nearby UAVs to defend against the eavesdropping. In particular, we consider a two-UAV scenario when one UAV

Trajectory Tracking of Autonomous Vehicle Based on Model Predictive Control With PID Feedback
IEEE transactions on intelligent transportation systems (Print), 2023 The simplified vehicle model often results in inaccuracy with respect to the conventional model predictive control (MPC) as it causes steady error in tracking control, which has negative implications for vehicle cornering.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Acute lymphoblastic leukaemia (ALL) is one of the most treatable forms of paediatric cancer; however, there is a substantial burden of treatment‐related toxicities (TRTs). In addition, the long‐term changes in children's health‐related quality of life (HRQoL) due to toxic treatments are not well understood.

Trajectory Control of an Air Cushion Vehicle.
Journal of the Japan Society for Aeronautical and Space Sciences, 1995 In this report several propulsion systems of air cushion vehicles are introduced, and a state feedback control law for trajectory control of an air cushion vehicle is proposed. We consider that the vehicle should be controlled so that it may not drift sideways for good driving performance.
