On the design of efficient optimal tube‐based robust model predictive control: Quasi‐H∞ approach

IET Control Theory & Applications, 2023
This paper proposes a tube‐based robust model predictive control (TMPC) scheme with an optimal tube for disturbance‐affected linear systems. In the literature on TMPC, there is no proper methodology to handle the considerable effects of the tube size on ...

Permissive Controller Synthesis for Probabilistic Systems [PDF]

Logical Methods in Computer Science, 2014
We propose novel controller synthesis techniques for probabilistic systems modelled using stochastic two-player games: one player acts as a controller, the second represents its environment, and probability is used to capture uncertainty arising due to, for example, unreliable sensors or faulty system components.

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

IET 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.
