Development of H∞ control strategy for a multi-wheeled combat vehicle
A vehicle dynamics controller for an 8 x 8 heavy combat vehicle utilising both torque vectoring and third and fourth axle steering is propoed. The control scheme is composed of two controllers: a feedforward zero side slip (ZSS) controller actuates the third and fourth axle steering angles and a …

Advanced control of MEMS probing devices
This work is aimed at developing a control-system theoretic approach for addressing certain performance issues that arise in micro-electro-mechanical systems (MEMS). In particular, it focuses on applications such as nano-positioning, where control design becomes necessary to meet high resolution, …

Fault tolerant control of active trailer steering systems for multi-trailer articulated heavy vehicles
Faults in a controlled plant often deteriorate the system performance. In severe cases, faults pose a risk of component damage, plant shutdown or even personnel safety. Fault Tolerant Control (FTC) aims at preventing the escalation of rectifiable faults to serious failure. A FTC system combines …

Ultracapacitor character analysis and its application in unified power quality conditioner as energy storage system
… with Ucap. The impact of UCAP model on its control and simulation is analyzed. From the analysis, UCAP based Energy Storage System can well fulfill the requirement of UPQC to provide high active power during transit time and improve the UPQC overall performance. The third part is Paper III. …

Dissipative systems theory : analysis and synthesis
… the strict bounded real lemma in the linear H control literature. We also provide characterization of a stable, strictly quadratic dissipative linear system in terms of a stabilizing solution to an algebraic Riccati equation (ARE). Connections between quadratic dissipative systems and finite …

The design of an H∞ voltage regulator for a predictive current controlled three phase PWM power converter
In this project, an H∞ controller is proposed as a DC voltage regulator for the predictive current controlled pulse with modulated (PWM) three-phase power converter to compensate the uncertainty caused by the predictive current controller. The H∞ theory has its unique approach to the uncertainty …

Strobe Light Effects On Stress and Avoidance Behavior in Fishes and Distribution of Zooplankton in Lake Oahe, South Dakota
… ±2.7, n=6) increased significantly compared to controls (5.0 ±1.1, 0.3 ±0.19, and 10.2 ±3.5, respectively) following 1 hour of exposure to strobe lights. After 7 h, plasma cortisol levels were similar to controls for all fish taxa. Fathead minnows showed no detectable response to strobe lights …

Improved Guidance, Navigation, and Control for Autonomous Underwater Vehicles: Theory and Experiment
This dissertation addresses attitude control and inertial navigation of autonomous underwater vehicles (AUVs). We present theoretical justification for using simplified models, derive system identification algorithms, and verify our results through extensive field trials. Although this research …

Diversifying crop systems by developing intercropping breeding strategies for improving forage yield and quality in oat-legume mixtures
… earlier than those grown under standard 16 h control conditions, while about 85% of plants produced a single seed, closely matching single-seed descent assumptions and substantially reducing space and labor requirements. We translated these findings into a standard operating procedure that …
