Abstract
Dynamics are playing an increasingly important role in many engineering
domains as these systems become more active and autonomous. Designing
a dynamic engineering system can be challenging. In this thesis, both the problem formulation and solution methods will be discussed for designing a dynamic engineering system. A case is made for the inclusion of both the physical and control system design into a single design formulation. A particular class of numerical methods known as direct transcription is identified as promising solution method. These principles are then demonstrated on the design of a wave energy converter, a device that captures energy present in ocean waves. This system is of particular interest since a successful design hinges on exploiting the natural dynamics of the interaction between the ocean waves and the physical wave energy converter. A number of numerical studies are presented that identify both novel and previously observed strategies for the maximizing energy production of a ocean wave energy converter.
