Utilizing structural knowledge of general nonlinear dynamics, the authors exploit the koopman operator to develop a systematic, data driven approach for constructing a linear representation in terms of higher order derivatives of the underlying nonlinear dynamics. In this framework, three data driven models are proposed and identified to approximate the infinite dimensional linear koopman operator through a method called extended dynamic mode decomposition (edmd). This document presents a methodology for using koopman operators to develop a linear representation of nonlinear systems from data. this linear representation then allows for the use of linear optimal control techniques like lqr, which are faster to compute than nonlinear control methods. This dissertation contributes fundamental theory and practical algorithms for the implementation of the koopman operator theory across distinctive types of robots.
