Model Predictive Satisficing Fuzzy Logic Control
Model-predictive control, which is an alternative to conventional optimal control, provides controller solutions to many constrained and nonlinear control problems. However, even when a good model is available, it may be necessary for an expert to...

A Theory of Satisficing Decisions and Control
The existence of an optimal control policy and the techniques for finding it are grounded fundamentally in a global perspective. These techniques can be of limited value when the global behavior of the system is difficult to characterize, as it may...

Transitions Between Hover and Level Flight for a Tailsitter UAV
UAV, tailsitter, VTOL aircraft, adaptive control, MRAC, trajectory tracking, Magicc Lab
Vertical Take-Off and Land (VTOL) Unmanned Air Vehicles (UAVs) possess several desirable characteristics, such as being able to hover and take-off or land in confined areas. One type of VTOL airframe, the tailsitter, has all of these advantages,...

Dynamic Modeling, Trajectory Generation and Tracking for Towed Cable Systems
towed cable system, trajectory generation, trajectory tracking, model predictive control, differential flatness, autopilot in the loop, aerial recovery
In this dissertation, we focus on the strategy that places and stabilizes the path of an aerial drogue, which is towed by a mothership aircraft using a long flexible cable, onto a horizontally flat orbit by maneuvering the mothership in the...

BYU Indoor Flight System Circa June 2011
This report documents the state of our indoor flight platform as of June 2011, the time of its first flight without a human in the loop. The report is intended to give enough detail that someone might have a reasonable hope of replicating our work...

Optimal Control Using a Neural/Evolutionary Hybrid System
One of the biggest hurdles to developing neurocontrollers is the difficulty in establishing good training data for the neural network. We propose a hybrid approach to the development of neurocontrollers that employs both evolutionary computation...

Verification of Digital Controller Verifications
small gain theorem, digital controller implementation, software verification, controller uncertainty
This thesis presents an analysis framework to verify the stablility property of a closed-loop control system with a software controller implementation. The usual approach to verifying stability for software uses experiments which are costly and...

Flexible machine tool control for direct, in-process dimensional part inspection
PC-DMIS, CMM, CNC, DMAC, coordinate measuring machine, machine tool, software controller, machine tool controller, measurement, in-process inspection, DCI, direct control
For some time now coordinate measuring machines have been an integral part of the shop floor. The goal has been to make coordinate measuring machines (CMMs) into tools that can easily be used by machinists to improve their manufacturing...

High-temperature Battery Calorimeter
A battery calorimeter was built for the measurement of thermal energy generation of high-temperature lithium–aluminum/iron sulfide battery cells, which are under development for electric vehicle propulsion and other energy storage applications....

Analysis and Design Tools for Structured Feedback Systems
Structured feedback systems, vulnerability, decentralized control, distributed control, signal structure, LTI system architecture
As we begin to analyze and construct extremely complex systems, a theory for understanding and designing the underlying architecture becomes very important. To move in the direction of a precise theory of architecture, this thesis will provide some...

Procedurally Rational Decision-Making and Control
Substantive rationality requires a decision-maker to be a utility maximizer; under this paradigm, the decision is paramount, and not dependent on the computational process used to obtain it. Procedural rationality is dependent on the method used to...

Designing Human-Centered Automation: Tradeoffs in Collision Avoidance System Design
Technological advances have made plausible the design of automated systems that share responsibility with a human operator. The decision to use automation to assist or replace a human operator in safety-critical tasks must account for not only the...

Semi-Autonomous Human-UAV Interfaces for Fixed-Wing Mini-UAVs
Sponsorship: DARPA, AFOSR. We present several human-robot interfaces that support real-time control of a small semi-autonomous UAV. These interfaces are designed for searching tasks and other missions that typically do not have a precise...

An Investigation of the Ward Leonard System for Use in a Hybrid or Electric Passenger Vehicle
Cody Telford, electric vehicle, Ward Leonard, motor testing, CVT, IVT, low cost, DC, LabView, shunt wound, DC motor, hybrid, variable voltage, control factor
Since the early 1900’s demand for fuel efficient vehicles has motivated the development of electric and hybrid electric vehicles. Unfortunately, some components used in these vehicles are expensive and complex. Today's consumer electric vehicles...

On-line Cartesian trajectory control of mechanisms along complex curves
New methods have been developed to control a mechanism's realtime Cartesian motion along spatially complex curves such as Non-Uniform Rational B-splines (NURBS). The methods dynamically map the critical trajectory parameters between parameter...

Dynamic Reconfigurable Machine Tool Controller
Reconfigurable Mechanism for Application Control; Direct control; CAD/CAM; Device driver; Dynamic-link library
This dissertation presents a dynamic reconfigurable control strategy based on the Direct Machining And Control (DMAC) research at Brigham Young University. A reconfigurable framework is proposed which will allow a machine tool to be controlled by...
