Design and simulation of a state-variable control system for the positioning of a milling table using the internal model principle
… a milling table must be capable of asymptotic tracking and disturbance rejection, and must be robust. The internal model principle is a general method developed by Davison, Desoer and Wonham which achieves asymptotic tracking and disturbance rejection, and is robust. In this thesis, a …

Output Regulation of Systems Governed by Delay Differential Equations: Approximations and Robustness
… the problem of robust geometric regulation for tracking and disturbance rejection of systems governed by delay differential equations. It is well known that geometric regulation can be highly sensitive to system parameters and hence such designs are not always robust. In particular, when …

Dynamic control of aerodynamic forces on a moving platform using active flow control
… between trailing edge aerodynamic flow control and airfoil motion in pitch and plunge is investigated in wind tunnel experiments using a two degree-of-freedom traverse which enables application of time-dependent external torque and forces by servo motors. The global aerodynamic forces and …

Physical Modeling and Control of Low Temperature Combustion in Engines
… Homogeneous Charge Compression Ignition (HCCI) and Partially Premixed Combustion (PPC), using physics-based models. The studied combustion concepts hold promise of reducing the emission levels and fuel consumption of internal combustion engines. A cycle-to-cycle model of HCCI, including heat …

An application of robust H₂/H[infinity] control synthesis to launch vehicle ascent by Tyler Nicklaus Hague.
… aerodynamic, fuel-sloshing, tail-wags-dog, and body-bending effects. The objective of the modern control synthesis approach presented here is to design compensation for pitch tracking and disturbance rejection. It combines techniques in optimal H2, optimal H [infinity], and sub-optimal …

Analysis and implementation of time-delay systems and networked control systems
… The presence of delays makes system analysis and control design much more complicated. Networked control systems where the delays are often random are typical cases of such systems.<br/><br/>For one particular category of time-delays systems, integral processes with dead time (IPDTs), the …

Linear-time invariant Positive Systems: Stabilization and the Servomechanism Problem
… known property of confining the state, output, and/or input variables to the nonnegative orphant, are of great practical importance, as the nonnegative property occurs quite frequently in numerous applications and in nature. These type of systems frequently occur in hydrology where they are used …
