A Survey of Quantum Lyapunov Control Methods [PDF]

open access: yesThe Scientific World Journal, 2013
The condition of a quantum Lyapunov-based control which can be well used in a closed quantum system is that the method can make the system convergent but not just stable.

Fuzzy inferencing-based path planning with a cyber-physical framework and adaptive second-order SMC for routing and mobility control in a robotic network

open access: yesIET Cyber-systems and Robotics, 2020
In this study, the authors address the problem of optimal routing and relative motion control in a network of robots. The path planning scheme has been designed using a fuzzy-based potential function employing optimal routing parameters.

Control Lyapunov Functions and Zubov's Method [PDF]

open access: yesSIAM Journal on Control and Optimization, 2008
For finite dimensional nonlinear control systems we study the relation between asymptotic null-controllability and control Lyapunov functions. It is shown that control Lyapunov functions may be constructed on the domain of asymptotic null-controllability as viscosity solutions of a first order PDE that generalizes Zubov's equation. The solution is also
