Design, Analysis, and Optimization of Vibrational Control Strategies
This dissertation presents novel vibrational control strategies for mechanical control-affine systems with high-frequency, high-amplitude inputs. Since these control systems use high-frequency, zero-mean, periodic inputs, averaging techniques are widely used in the analysis of their dynamics. By …

Exploration of Vibrational Control of Two Underactuated Mechanical Systems
Control of underactuated mechanical systems is of interest as it allows for control authority over all of a system's degrees of freedom without requiring actuation of the full system. In addition to this, open-loop control of a system provides the advantage of applying to systems with unmeasurable …

Vibrational Control of a Cantilever Beam Using Sensor and Actuator Averaging Methods
… to model parameter uncertainty. We develop a controller to actively control cantilever beam vibration using accelerometer input. The controller is a classic single-sensor single-actuator system that achieves a phase margin of 31° and bandwidth of 3.5 kHz. We then use the same controller but …

Vibrational control: Application to a laser-illuminated reaction and extension to nonlinear functional differential equations
Vibrational Control method is an open-loop control technique which utilizes zero mean parametric excitations to modify the behavior of dynamical systems in a desired manner. It may be used where conventional methods such as feedback or feedforward techniques fail due to restricted sensing and/or …

Vibrational and adaptive control of a class of distributed parameter systems described by parabolic partial differential equations
Two nonclassical control techniques, vibrational control and direct model reference adaptive control, for a class of distributed parameter systems described by parabolic partial differential equations (PDE's) are discussed.

Vibrationally enhanced associative photodesorption of H2 (D2) from Ru(0001) : quantum and classical approaches
… channels for energy exchange which makes the control of surface reactions more difficult than the control of reactions in the gas phase. In fact, the quantum yield of surface photochemical reactions is often notoriously small. One of the goals of the present thesis is to suggest, on the basis …
