150 Years of the Mass Action Law
(Journal article; Peer reviewed, 2015)This year we celebrate the 150th anniversary of the law of mass action. This law is often assumed to have been “there” forever, but it has its own history, background, and a definite starting point. The law has had an ... -
A 3D reactive collision avoidance algorithm for underactuated underwater vehicles

A 3DOF Path-Following Controller for a Non-Directionally Stable Vessel with Slow Thruster Dynamics
(Peer reviewed; Journal article, 2021)In this paper, a 3DOF path-following controller for an electric double-ended passenger ferry prototype is presented. The controller is formulated through a 3-step backstepping approach, taking into consideration several ... -
A 3D Reactive Collision Avoidance Algorithm for Underactuated Vehicles
(Journal article; Peer reviewed, 2019)This paper presents a 3D reactive collision avoidance algorithm for vehicles with underactuated dynamics. The underactuated states cannot be directly controlled, but are controlled indirectly by steering the direction of ... -
A Comparative Study of Different Control Structures for Flight Control with New Results
(Journal article; Peer reviewed, 2018)This paper presents several different control structures that facilitate flight control and does a comparison between them. Specifically, this paper considers command-filtered backstepping, nonlinear dynamic inversion ... -
A computational pipeline for quantification of mouse myocardial stiffness parameters
(Journal article; Peer reviewed, 2014)The mouse is an important model for theoretical–experimental cardiac research, and biophysically based whole organ models of the mouse heart are now within reach. However, the passive material properties of mouse myocardium ... -
A computationally efficient model predictive control scheme for space debris rendezvous
(Journal article; Peer reviewed, 2019)We propose a non-linear model predictive scheme for planning fuel efficient maneuvers of small spacecrafts that shall rendezvous space debris. The paper addresses the specific issues of potential limited on-board computational ... -
A control framework for biologically inspired underwater swimming manipulators equipped with thrusters
(IFAC Proceedings series;, Journal article; Peer reviewed, 2016)In this paper we present a control framework for a novel biologically inspired underwater swimming manipulator (USM) equipped with thrusters. The framework consists of a kinematic part and a dynamic part. The kinematic ... -
A control framework for snake robot locomotion based on shape control points interconnected by Bézier curves
(Journal article; Peer reviewed, 2012)This paper presents a control framework for shape control of snake robots for the purpose of locomotion. An advantage of the framework is that it allows the macroscopic shape of a snake robot to be controlled explicitly ... -
A Cyber-Physical Systems Approach for Implementing the Receding Horizon Optimal Power Flow in Smart Grids
(Journal article; Peer reviewed, 2017)Two Major challenges in securing reliable Optimal Power Flow (OPF) operations are: (i) fluctuations induced due to renewable generators and energy demand, and (ii) interaction and interoperability among the different ... -
A deep learning enabler for non-intrusive reduced order modeling of fluid flows
(Journal article; Peer reviewed, 2019)In this paper, we introduce a modular deep neural network (DNN) framework for data-driven reduced order modeling of dynamical systems relevant to fluid flows. We propose various DNN architectures which numerically predict ... -
A Distributed Algorithm for Scenario-based Model Predictive Control using Primal Decomposition *
(Journal article; Peer reviewed, 2018)In this paper, we consider the decomposition of scenario-based model predictive control problem. Scenario MPC explicitly considers the concept of recourse by representing the evolution of uncertainty by a discrete scenario ... -
A distributed parameter systems view of control problems in drilling
(Journal article; Peer reviewed, 2015)We give a detailed view of estimation and control problems raised by the drilling process where the distributed nature of the system cannot be ignored. In particular, we focus on the transport phenomena in Managed Pressure ... -
