A Reactive Collision Avoidance Algorithm for Vehicles with Underactuated Dynamics
(Journal article; Peer reviewed, 2017)This paper presents a reactive collision avoidance algorithm, which avoids both static and moving obstacles by keeping a constant avoidance angle between the vehicle velocity vector and the obstacle. In particular, we ... -
Adaptive Control of a Nanopositioning Device
(Journal article; Peer reviewed, 2012)High-bandwidth tracking control is desirable in many nanopositioning applications, including scanning probe microscopy. Typical nanopositioner designs have several sources of uncertainty which can degrade control performance, ... -
Almost Global Three-Dimensional Path-Following Guidance Law for Arbitrary Curved Paths
(Peer reviewed; Journal article, 2023)Motivated by aircraft applications, we revisit the path-following guidance problem in three dimensions. First, by formulating the path-following error directly in the inertial frame, we propose a class of guidance laws for ... -
Combining Q-learning and Deterministic Policy Gradient for Learning-Based MPC
(Peer reviewed; Journal article, 2023)This paper considers adjusting a fully parametrized model predictive control (MPC) scheme to approximate the optimal policy for a system as accurately as possible. By adopting MPC as a function approximator in reinforcement ... -
Direct predictive control of a first-order quasilinear hyperbolic PDE
(Journal article; Peer reviewed, 2019)We present a method for the boundary controlof a system governed by one hyperbolic PDE with a non-localcoupling term by state feedback. The method is an extensionof recently developed controllers for semilinear systems. ... -
Direction Following Control of Planar Snake Robots Using Virtual Holonomic Constraints
(Journal article; Peer reviewed, 2015)This paper investigates the problem of direction following for planar snake robots. The control objective is to regulate the linear velocity vector of the snake robot to a constant reference while guaranteeing boundedness ... -
Economic model predictive control for snake robot locomotion
(Journal article; Peer reviewed, 2019)Abstract— In this work, the control of snake robot loco-motion via economic model predictive control (MPC) is studied.Only very few examples of applications of MPC to snake robotsexist and rigorous proofs for recursive ... -
Explicit Backstepping Kernel Solutions for Leak Detection in Pipe Flow Networks Containing Loops
(Peer reviewed; Journal article, 2023)A recursive procedure to obtain explicit expressions to a set of observer backstepping kernel equations for an interconnection (cascade) of N+1 systems of 2×2 linear hyperbolic PDEs, N>0 an integer, for use in leak detection ... -
Leak detection, size estimation and localization in water distribution networks containing loops
(Journal article, 2022)We consider the problem of leak detection, size estimation and localization of leaks in a water distribution network with ring topology, with flow and pressure measurements taken at junctions only. The pipeline system is ... -

Stability analysis of snake robot locomotion based on averaging theory
(Journal article; Peer reviewed, 2011)This paper investigates the controllability and stability properties of a planar snake robot influenced by anisotropic viscous ground friction. An analysis of the model shows that any asymptotically stabilizing control law ... -
Vehicle Safety of the Velocity Obstacle Algorithm
(Peer reviewed; Journal article, 2020)This paper presents a mathematical analysis of the velocity obstacle algorithm applied to a nonholonomic vehicle for avoiding a moving obstacle in the plane. The velocity obstacle algorithm can be used for local navigation ... -
Voronoi-Based Deployment of Multi-Agent Systems
(Peer reviewed; Journal article, 2019)This paper considers a decentralized control scheme for Voronoi-based deployment of discrete-time multiagent dynamical systems within multi-dimensional static convex polytopic environments. The deployment objective is to ...
