In the present study, a Model Predictive Control (MPC) - based, Energy Management Strategy (EMS) is proposed, aiming at the minimisation of the fuel consumption of vessels with hybrid propulsion and power supply. This approach is capable of utilising online information regarding realistic future predictions of the propulsive power demand,...

Public Address systems that include a setup with at least one microphone and speaker can suffer from acoustic feedback. This results in an annoying howling effect which can damage hardware and human hearing. To solve this issue, an adaptive filter that estimates the feedback path and uses this estimate to cancel the feedback can be designed....

This report is written as part of the Bachelor Graduation Project in the third year of the Electrical Engineering Bachelor programme at the Delft University of Technology. This report is made by a subgroup that is part of a larger project dedicated to finding a solution to frequency feedback in electroacoustic systems, also known as the Larsen...

The most promising method for acoustic feedback control in public address systems is adaptive feedback cancellation (AFC). This approach is based on making an estimation of the room impulse response, which is used to subtract an estimate of the feedback from the microphone signal. A postfilter is often used to improve the performance of such an...

This thesis report focuses on possible methods of digital implementation of motional feedback in a bass loudspeaker. In this thesis, the control system will be created for a monopole and a dipole speaker specifically. It does so by sketching the outlines of such a system and examining possible designs for the components required to suppress...

The displacement of a loudspeaker cone is not linearly proportional to the voltage/current at its input provided. This is due to electrical and mechanical limitations. The distortion is more noticeable at lower frequencies. This report is one of two reports, that will explain how to minimize this distortion. The motion of the loudspeaker cone...

Driving with driver assistance systems utilising haptic shared control (HSC) can lead to annoyance, or even disuse, when the intent of both entities differs. In order to increase compliance and acceptance of these systems, this study explores two types of visual information projected onto the outside scenery. One visualisation portrays only the...

In the Intensive Care Units (ICU) patients are exposed to many, continuous and highly stressors, such as medical alarms, which contribute to the development of psychological issues, such as delirium, anxiety disorders and post-traumatic stress disorders (PTSD). These psychological issues have a negative influence on the patients’ healing process...

As computer science lies at the heart of almost all technological progress, widespread computer science education, and particularly programming education, is of great importance. In order to reach a large group of students, secondary schools can play an important role. However, students have difficulty learning programming concepts. Programming...

In this thesis, we focus on flexible haptic feedback applications which rely on the sensation of touch to display a feedback to the user that establishes a system to user interaction. Piezocomposites made of piezoceramic and polymer phases can be used here due to their high flexibility and piezoelectric properties that enable them to deform...

An integral part of creating compelling and useful immersive virtual environments is the presence of haptic feedback, where both kinesthetic and cutaneous feedback convey unique information critical to object handling and manipulation. State-of-the-art haptic gloves are broadening the workspace and degrees of freedom for hand motion in VR,...

Tele-impedance augments classical teleoperation by enabling the human operator to actively command remote robot stiffness. Hereby, an essential strategy used by humans to successfully interact with the unstructured environment complements remote robot-environment interaction. However, literature lacks awareness of benefits and disbenefits of...

Laparoscopic or minimally invasive surgery (MIS) has seen a lot of development. For the patient, laparoscopic surgery has many benefits. However, for surgeons this is not the case. For example, laparoscopic grasper design exhibit play and hysteresis during surgical tasks such as grasping and palpating. This impedes haptic feedback, resulting in...

Over the past decades, the technological improvements in computing power, software and projection systems enabled driving simulators to become a cost-effective tool to perform research activities and train novel drivers. Today, driving simulators are widely used for studying the interaction of driver and vehicle system, developing new vehicles...

This document details a lab study into bimanual synchronised haptics, followed by the design of a product that can be used in combination with the SenseGlove to provide their wearer with haptic feedback based on how they operate a steering mechanism in Virtual Reality. The Dutch Ministry of Defense approached SenseGlove B.V., a company...

Lambers, Jorrinde (author)
Current upper-limb prostheses are often rejected as a result of high activation forces that are needed for control. Another reason for rejection is the absence of appropriate proprioceptive feedback. In this study, a pneumatic control system was designed that decreased the activation forces and where proprioceptive feedback was provided. The...

Reflexes and co-contraction are the two mechanisms used for effective limb control when humans face unexpected perturbations in their daily activities. When the environment has reduced stability margins, reflexes are tempered due to the oscillations caused by the neural time delay of the reflexive pathways. An explanation is that reflexes adapt...

Due to the dramatic increase in enrollments in the TU Delft Bachelor of Computer<br/>Science, the workload for teaching assistants and instructors has skyrocketed. To<br/>reduce this workload, automated tools can be used to make the grading process easier. This paper describes the development of AuTA (Automatic Teaching Assistant), a tool that...

In this report the finger vibrotactile subsystem of the SoftGlove wearable haptic feedback glove is discussed. This system is an upgrade over the vibrotactile feedback that the current SenseGlove haptic feedback glove provides. The designed system consists of a linear resonant actuator (LRA) on each finger, which is controlled by a dedicated LRA...
