Friction‐Aware Force‐Realizable Safety Control for Four‐Wheel Independently Steered and Driven Mobile Robots

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Safety‐critical control remains a major challenge for four‐wheel independently steered and driven (4ISD) mobile robots, where high‐accuracy path tracking and obstacle avoidance must be achieved under over‐actuated steering–driving coordination, tire–ground friction limits, and wheel‐torque constraints.

Impulsive Thruster Control for Spacecraft Docking: A Lyapunov Approach

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT In this work, we propose a novel discontinuous impulsive controller for nonlinear systems that admit continuous‐time stabilizing controllers. Specifically, we develop a technique for generating discrete control pulses of short duration based on the Lyapunov candidate function associated with a continuous‐time controller. Our method uses a real‐

Deep Reinforcement Learning‐Based Control for Real‐Time Hybrid Simulation of Civil Structures

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Real‐time Hybrid Simulation (RTHS) is a cyber‐physical technique that studies the dynamic behavior of a system by combining physical and numerical components that are coupled through a boundary condition enforcer. In structural engineering, the numerical components are subjected to environmental loads that become dynamic displacements of the ...

Backstepping Control of Electro-Hydraulic Arm

2018 6th International Conference on Control Engineering & Information Technology (CEIT), 2018
In this study, positioning control of the electro hydraulic systems is considered. Backstepping control strategy is designed by defining an auxiliary error signal. The performance of the controller is investigated by conducting numerical simulations. From the simulation results, it is seen that the control objective achieved successfully.

Backstepping control of the one-phase stefan problem [PDF]

2016 American Control Conference (ACC), 2016
In this paper, a backstepping control of the one-phase Stefan Problem, which is a 1-D diffusion Partial Differential Equation (PDE) defined on a time varying spatial domain described by an ordinary differential equation (ODE), is studied. A new nonlinear backstepping transformation for moving boundary problem is utilized to transform the original ...

Contextual Learning of New Meanings for Familiar Words: Perturbation of Original Meanings Occurs Without Deliberate Study

Language Learning, EarlyView.
Abstract The present study investigated learning new meanings of known words from reading, following Hulme et al.’s (2018) study. English speakers read four short stories containing 16 critical words (i.e., familiar word forms assigned invented secondary meanings).

Backstepping controller synthesis and characterizations of incremental stability [PDF]

Systems & Control Letters, 2013
Incremental stability is a property of dynamical and control systems, requiring the uniform asymptotic stability of every trajectory, rather than that of an equilibrium point or a particular time-varying trajectory. Similarly to stability, Lyapunov functions and contraction metrics play important roles in the study of incremental stability.
