Radar-based Maritime Collision Avoidance using Dynamic Window
(Journal article; Peer reviewed, 2018)Collision avoidance systems are a key ingredient in developing autonomous surface vehicles (ASVs). Such systems require real-time information about the environment, which can be obtained from transponder-based systems or ... -
Range Anxiety Alleviation for Electric Vehicles using a Dual Extended Kalman Filter with a Nonlinear Battery Model
(Master thesis, 2017)The purpose of this thesis was to find a solution to combat range anxiety in electric vehicles (EV). Range anxiety was defined as the fear that the driver will not reach their destination and is a major barrier to increase ... -
Range-based Target Localization and Pursuit with Autonomous Vehicles: An Approach using Posterior CRLB and Model Predictive Control
(Peer reviewed; Journal article, 2020)We address the general problem of multiple target localization and pursuit using measurements of the ranges from the targets to a set of autonomous pursuing vehicles, referred to as trackers. We develop a general framework ... -
Rare event chance-constrained optimal control using polynomial chaos and subset simulation
(Journal article; Peer reviewed, 2019)This study develops a chance–constrained open–loop optimal control (CC–OC) framework capable of handling rare event probabilities. Therefore, the framework uses the generalized polynomial chaos (gPC) method to calculate ... -
Reactive Collision Avoidance - Safe navigation in a dynamic cluttered environment
(Master thesis, 2018)Collision-free navigation in unknown environments is an essential quality for any autonomous vehicle. In this thesis, a reactive collision avoidance algorithm is presented for vehicles constrained by a unicycle nonholonomic ... -
Reactive Collision Avoidance for Nonholonomic Vehicles in Dynamic Environments with Obstacles of Arbitrary Shape
(Peer reviewed; Journal article, 2021)Over the recent years, there has been an increasing interest in autonomous systems. Consequently, the problem of avoiding static and dynamic obstacles without human interference has gained a lot of attention. Avoiding ... -
Reactive Collision Avoidance for Underactuated Surface Vehicles using the Collision Cone Concept
(Chapter, 2021)Avoiding collisions is a crucial task for autonomous systems. Many strategies for avoiding obstacles have been proposed, yet the problem of having underactuated dynamics is rarely addressed in previous studies of collision ... -
Real time decoding of color symbol for optical positioning system
(Journal article; Peer reviewed, 2015)This paper presents the design and real-time decoding of a color symbol that can be used as a reference marker for optical navigation. The designed symbol has a circular shape and is printed on paper using two distinct ... -
Real Time Impedance identification of Li-Polymer Battery with Kalman Filter
(Master thesis, 2017)In a study of a new and an aged lithium-polymer battery cell, a joint Unscented Kalman Filter coupled with a non-linear equivalent circuit battery model formed the basis for on-line identification of the battery impedance ... -
Real time lobster posture estimation for behavior research
(Chapter; Peer reviewed, 2017)In animal behavior research, the main task of observing the behavior of an animal is usually done manually. The measurement of the trajectory of an animal and its real-time posture description is often omitted due to the ... -
Real time optimization of systems with fast and slow dynamics using a lookahead strategy
(Chapter, 2020)Systems with fast and slow dynamics give rise to objectives in different time scales which may not be aligned. The existing dynamic optimal control methods might become computationally infeasible due to the fine discretization ... -
Real Time Phasor Estimation based on Recursive Prony with Several Channels of One PMU
