Robust TDOA/FDOA estimation from emitter signals for hybrid localization using UAVs

open access: yesDefence Technology, 2022
This paper considers the time difference of arrival (TDOA) and frequency difference of arrival (FDOA) estimation problem for joint localization using unmanned aerial vehicles (UAVs), involving range migration (RM) and Doppler ambiguity within observation

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

open access: yesIET 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 ...

Design of auto‐tuning‐based adaptive controllers for voltage source converters with inductive loads

open access: yesIET Power Electronics, 2023
This paper presents an auto‐tuning method for dc‐ac voltage source converters (VSCs) with an inductive load that is based on the modified relay feedback test (MRFT).

Evolutionary Synthesis of HVAC System Configurations: Algorithm Development. [PDF]

open access: yes, 2008
This paper describes the development of an optimization procedure for the synthesis of novel heating, ventilating, and air-conditioning (HVAC) system configurations. Novel HVAC system designs can be synthesized using model-based optimization methods. The

A System-Level Approach to Controller Synthesis [PDF]

open access: yesIEEE Transactions on Automatic Control, 2019
Biological and advanced cyberphysical control systems often have limited, sparse, uncertain, and distributed communication and computing in addition to sensing and actuation. Fortunately, the corresponding plants and performance requirements are also sparse and structured, and this must be exploited to make constrained controller design feasible and ...

Adaptive constrained population extremal optimisation‐based robust proportional‐integral‐derivation frequency control method for an islanded microgrid

open access: yesIET Cyber-systems and Robotics, 2021
The expected penetration of renewable sources is driving the islanded microgrid towards uncertainties, which have highly influence the reliability and complexities of frequency control.

Technical report: PID design of second‐order non‐linear uncertain systems with fractional order operations

open access: yesIET Cyber-systems and Robotics, 2021
This study considers a control problem related to the regulation of fractional‐order systems controlled by fractional order proportional‐integral‐derivative controllers (PIλDμ).

Synthesis of communicating controllers for distributed systems [PDF]

open access: yesIEEE Conference on Decision and Control and European Control Conference, 2011
We consider the control of distributed systems composed of subsystems communicating asynchronously; the aim is to build local controllers that restrict the behavior of a distributed system in order to satisfy a global state avoidance property. We model our distributed systems as communicating finite state machines with reliable unbounded FIFO queues ...

Permissive Controller Synthesis for Probabilistic Systems [PDF]

open access: yesLogical 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.

Evolutionary selection of biofilm-mediated extended phenotypes in Yersinia pestis in response to a fluctuating environment

open access: yesNature Communications, 2020
Yersinia pestis, the causative agent of plague, can change its biofilm production to influence the dynamics of flea-borne transmission. Here, the authors sequence Y.
