Development of a Model-based Control Strategy for Autonomous Vehicle Collision Avoidance
(University of Waterloo, 2022-09-29)Human inattention is the leading cause of traffic accidents in many regions around the world. Autonomous vehicle technologies are rapidly emerging with the aim to remove the human factor in key driving procedures, such as ... -
Displace and Urbanized: Or Why We Build
(University of Waterloo, 2019-01-11)I embarked on this research with the aim to study the relationship between the city and the flood, understanding the waterfront as some blurred edge where wild and human forces mix. My hope was to propose a design strategy ... -
A Foot Placement Strategy for Robust Bipedal Gait Control
(University of Waterloo, 2008-05-23)This thesis introduces a new measure of balance for bipedal robotics called the foot placement estimator (FPE). To develop this measure, stability first is defined for a simple biped. A proof of the stability of a simple ... -
A Framework for Coordinated Control of Multi-Agent Systems
(University of Waterloo, 2006)Multi-agent systems represent a group of agents that cooperate to solve common tasks in a dynamic environment. Multi-agent control systems have been widely studied in the past few years. The control of multi-agent ... -
The Human Immune System: A Challenging Control Problem
(University of Waterloo, 2004)This work deals with the control of the human immune system. A standard immune system model is modified by introducing control signals corresponding to drug cocktail and immune suppressor treatments. The ultimate ... -
A hybrid inverse dynamic-neural network approach to lower limb exoskeleton control
(University of Waterloo, 2022-08-22)A powered machine that is wearable over all or part of the human body can be referred to as a powered exoskeleton. The role of powered exoskeletons is usually to provide ergonomic structural support while using motor power ... -
Localized-Based Control Algorithm For Passenger Ride Comfort
(University of Waterloo, 2014-09-15)In this thesis, a new localized-based suspension control strategy is developed, simulated and validated with experimental results. Basic concepts of mathematical vehicle models, suspension systems, and conventional control ... -
Mechanics and Control of Human Balance
(University of Waterloo, 2011-04-18)A predictive, forward-dynamic model and computer simulation of human gait has important medical and research applications. Most human simulation work has focused on inverse dynamics studies to quantify bone on bone forces ... -
Modelling, Control, and Planning of Microgrids for Power Quality Assurance
(University of Waterloo, 2020-04-15)This thesis considers power quality improvement for microgrids penetrated with nonlinear loads at two levels: 1) at the device level, which is carried out through the distributed generators’ (DGs’) controllers on a ... -
Nano Positioning Control Using Magnetostrictive Actuators
(University of Waterloo, 2007-05-18)The focus of this thesis is on the development of control systems for nano- positioning actuators using magnetostrictive materials. Magnetostrictive materials have large strokes and fast responses. However, they are ... -
Nonlinear and Geometric Controllers for Rigid Body Vehicles
(University of Waterloo, 2018-10-18)In this thesis we investigate the motion control problem for a class of vehicles C V , which includes satellites, quadrotors, underwater vehicles, and tailsitters. Given a globally represented model of C V , and a curve, ... -
A Novel Back-Off Algorithm for the Integration Between Dynamic Optimization and Scheduling of Batch Processes Under Uncertainty
(University of Waterloo, 2019-12-04)This thesis presents a decomposition algorithm for obtaining robust scheduling and control decisions. It iteratively solves scheduling and dynamic optimization problems while approximating stochastic uncertainty through ... -
Precision Control of High Speed Ball Screw Drives
(University of Waterloo, 2009-01-16)Industrial demands for higher productivity rates and more stringent part tolerances require faster production machines that can produce, assemble, or manipulate parts at higher speeds and with better accuracy than ever ... -
Precision Landing of a Quadrotor UAV on a Moving Target Using Low-Cost Sensors
(University of Waterloo, 2014-09-16)With the use of unmanned aerial vehicles (UAVs) becoming more widespread, a need for precise autonomous landings has arisen. In the maritime setting, precise autonomous landings will help to provide a safe way to recover ... -
Redundant Hybrid Cable-Driven Robots: Modeling, Control, and Analysis
(University of Waterloo, 2019-08-29)Serial and Cable-Driven Parallel Robots (CDPRs) are two types of robots that are widely used in industrial applications. Usually, the former offers high position accuracy at the cost of high motion inertia and small workspace ... -
Robust and Adaptive Control Methods for Small Aerial Vehicles
(University of Waterloo, 2012-09-26)Recent advances in sensor and microcomputer technology and in control and aeroydynamics theories has made small unmanned aerial vehicles a reality. The small size, low cost and manoueverbility of these systems has positioned ... -
The Role of Affect in Commercializing New Ideas
(University of Waterloo, 2008-07-22)Psychological attachment to an entrepreneurial opportunity may motivate the entrepreneur to persevere but can also bias decisions made in the entrepreneurial process, especially on market entry. This thesis investigates ... -
Stability and Performance for Two Classes of Time-Varying Uncertain Plants
(University of Waterloo, 2009-10-02)In this thesis, we consider plants with uncertain parameters where those parameters may be time-varying; we show that, with reasonable assumptions, we can design a controller that stabilizes such systems while providing ... -
