The world population is growing rapidly and the demand for healthy food grows with it. Greenhouse cultivation provides an efficient way to grow crops in a protected and controlled environment. In the past, many greenhouse control algorithms have been developed. How- ever, the majority of these algorithms rely on an explicit parametric model...

At DCSC, research is conducted in the field of multi-agent systems. While this research often takes a theoretical approach, there is a growing need to verify the research on an experimental platform. In this way, the newly developed methods can be experimentally validated. For this purpose, a compact system is developed for localization and pose...

In this work we consider the problem of cooperative formation control between heterogeneous agents when time-varying delays and/or packet loss are present. Specifically, we introduce a control law for nonlinear fully actuated mechanical agents that separates the cooperative coordinates from the local coordinates, which removes the necessity for...

A well-established method for finding the optimal control policy for a given dynamical system is to solve the problem iteratively going from its terminal state "backwards" in time, known as Dynamic Programming Algorithm. For a generic problem with discrete state/action space, the algorithm has computational complexity of <i>O(NM)</i> for <i>N</i...

Accurate indoor localization is essential for autonomous robotic agents to perform tasks ranging from warehouse management to remote sensing in greenhouses. Recently Ultra Wideband (UWB) distance measurements have been used to estimate position and velocity indoors. These UWB-measurements are known to be corrupted by a varying bias. Besides,...

Electric Vehicles (EVs) are considered a promising solution when it comes to reducing CO2 emissions in the transport sector. To accommodate for large numbers of EVs, a considerable amount of additional charging infrastructure must be installed. Simultaneous charging of large quantities of EVs leads to peak loads in the energy grid. One way to...

Recent advances on the design of autonomous mobile agents have motivated the use of the latter in persistent surveillance tasks with applications in agriculture, information gathering and search and rescue missions. In these tasks the goal is to design agents’ paths so as every point in the area of interest is covered more than once. In...

Development of the autonomous vehicle has been a trending topic over the last few years. The automotive industry is continuously developing Advanced Driver-Assistance Systems (ADAS) that partially take over the driver’s workload. This has resulted in an increase in vehicle safety and a decrease in fatal crashes [1]. Full vehicle autonomy has not...

Worldwide roughly 80% of heating and cooling systems in the building sector are currently dominated by fossil-fuel technologies. These systems, known as Heating, Ventilation and Air Conditioning (HVAC) systems have contributed to global climate change and global warming. These effects are the consequence of the increasing demand of HVAC systems...

In recent years there has been an increasing interest in formation flying with many lightweight spacecraft, as satellite missions can potentially become cheaper and more flexible. An example of such mission is the Silicon Wafer Integrated Femtosatellites mission, consisting of 100 to 1000 spacecraft with a mass of 0.1 kg. Due to modest control...

A numerically tractable Stochastic Model Predictive Control (SMPC) strategy using Conditional Value at Risk (CVaR) optimization for discrete-time linear time-invariant systems, with state and input constraints, subject to additive uncertainty, is presented. SMPC strategies make use of the probabilistic description of uncertainty to define chance...

Aircraft lifespan can be extended by upgrading and modernizing the electrical subsystems and instruments. However, this often introduces increased power demands and heat generation that the aircraft was not originally designed for and can result in a reduced flight performance and increased wear. Netherlands Aerospace Centre (NLR) and the...

With the decrease in sensor and actuator costs decentralized control strategies have become increasingly attractive, aiming to use multiple simpler robots for achieving a global objective. The problem of reaching the global objective generally results in a consensus problem requiring communication amongst the agents. The cooperative manipulation...
