Hybrid passivity and finite-gain properties of reset systems: An application to stability analysis in the frequency domain

Reset control is a "simple" nonlinear control strategy that has the potential of being widely adopted and improving the performance of systems traditionally controlled with PIDs. Lack of suitable methods for proving stability, that are in line with the current industrial practice, hampers the wider acceptance of reset control. In this thesis,...

A Bayesian Approach for Active Fault Isolation with an Application to Leakage Localization in Water Distribution Networks

This thesis describes the application of a stochastic active fault diagnosis method for localising leaks in a Water Distribution Network (WDN) under parametric uncertainty, in order to localise leaks faster and more reliable compared to non-invasive state-of-the-art methods. Output residual Probability Distribution Functions (PDFs) for a...

Comparing electric vehicle charging strategies in stochastic microgrid optimization

Renewable energy sources, e.g. solar energy and wind energy, have gained popularity as an alternative means of energy production as they do not reinforce global warming. In addition, more and more electrical appliances (e.g. electric vehicles, induction cookers, and heat pumps) are used as a substitute for appliances that need non-renewable...

Decentralized coordination for area surveillance purposes

The area surveillance problem is the problem of surveying a known or an unknown area with the main purpose of detecting objects. This thesis will tackle the problem of how to employ a group of mobile-sensors for surveying an unobstructed area in an optimal manner. The mobile-sensors should make use of their onboard computers and they should...

Signal Group-based Look-ahead Traffic Signal Control

Traffic signal controllers have been around since the late sixties of the 19th century and since then they have played an increasing role in (urban) traffic management. Over the years many different algorithms have been developed and in Dutch practice actuated control is mostly used. Actuated control and other similar approaches apply variable...

Control of biological phosphorus removal in an oxidation ditch using simple sensors

Control of wastewater treatment plants has received more attention as a method to improve nutrient removal processes. Improved nutrient removal, results in an increased effluent quality, whilst minimising the energy consumption. Aeration control of oxidation ditches often focuses on adjusting the aeration intensity based on the nitrogen removal...

Optimal traffic light control: performance evaluation applying a general evaluation methodology

The ongoing increase in urbanization and traffic congestion creates an urgent need to operate our transportation systems with maximum efficiency. Traffic signal control optimization is considered one of the main ways to solve traffic problems in urban networks. In publications in the field of intelligent transportation systems, a vast amount of...

Spline-based Trajectory Generation for Autonomous Truck-Trailer Vehicles in Low Speed Highway Scenarios

Trajectory generators are designed to create reference paths that are parametrized by time as well as by velocity or acceleration. In the literature, it has been noted that often path planners are the last step in the planning module of autonomous truck-trailer vehicles, which results in a collision-free track. A trajectory generator can improve...
