Sensing String Displacement as a Control Modality: Sensor Design and Implementation
… across cultures, DMIs in which strings are the primary control interface remain rare. In an effort to support the creation of new stringed DMIs we describe an approach to instrument design in which the static 2-dimensional displacement of strings is a primary control modality. We review a …

Phase control of delta-connected single-phase grid-forming inverters for auxiliary signal injection
This thesis presents a strategy for controlling the phase differences of a three-phase voltage source made up of single-phase droop-controlled grid forming inverters arranged in a delta configuration. We begin by deriving the simplified $dq$ model of a three-phase ($3\phi$) grid-forming inverter …

Experimental evaluation of some feedforward control models for binary distillation
In this study four different feedforward control models were derived in order to hold overhead composition fixed. This task was performed by literature review on distillation dynamics and simulation, and automatic control system applications. A theoretical analysis of feedback control compared to …

Pulsatile Electropolishing of Nitinol Stents
… metallic oxide. This thesis aims to shift the primary control of the electropolishing e_ect from electrolyte variables to a combination of potential variation and hydrodynamic interference. Traditionally this is achieved with one continuous mass removal process that operates after a steady …

Socialization of coping with peer victimization and negative emotionality: Interactive contributions to children's responses to stress and depressive symptoms
… symptoms over time; specifically, secondary control engagement suggestions predicted fewer symptoms for all children, and disengagement coping suggestions predicted fewer symptoms for children with both high negative emotionality and high exposure to peer victimization. Active socialization …

A study of aircraft agility
… model considers the body axes angular rates as control variables and is accordingly referred to as the body rate model. The second model is a rigid body model featuring rotational dynamics governed by the primary control surface deflections. The body rate model is intermediate between a …

Contributions of maternal emotional awareness to socialization of coping
… that maternal emotional awareness predicted more primary control engagement suggestions (suggestions to address the source of stress or the accompanying emotional response) concurrently and over time, and predicted more distress responses concurrently. Emotional awareness predicted fewer secondary …

Modeling, simulation, and control design of electro-mechanical dynamics in heterogeneous power systems
… generators and grid forming inverters with droop control, virtual synchronous machine control, and dispatchable virtual oscillator control is developed. To mitigate model complexity and facilitate analytical understanding, this framework employs reduced-order models that are applicable for …

Char Reaction Kinetics in a Transport Gasifier
… equations were developed as a function of the primary control variables: oxygen-to-carbon ratios, temperature, coal type, and water content. Bench scale tests were preformed using a pressurized fluidized bed reactor (PFBR) to simulate the conditions of a transport gasifier. From these …

Control design techniques for constrained positive compartmental systems with applications to air traffic flow management
… methods presented are based on sliding mode control theory and linear programming theory. Contributions of this work are methods which: (a) react in real time to changing flow rate constraints, and (b) use routing parameters to satisfy time varying capacity constraints for linear, uncertain …
