Derivative-Based Koopman Operators for Real-Time Control of Robotic Systems [article]

Giorgos Mamakoukas, Maria L. Castano, Xiaobo Tan, Todd D. Murphey
2021 arXiv   pre-print
When combined with control, the Koopman representation of the nonlinear system has marginally better performance than competing nonlinear modeling methods, such as SINDy and NARX.  ...  This paper presents a generalizable methodology for data-driven identification of nonlinear dynamics that bounds the model error in terms of the prediction horizon and the magnitude of the derivatives  ...  One can draw from many control schemes, including linear quadratic regulator (LQR) [3] , linear model predictive control (LMPC) [4] , nonlinear model predictive control (NMPC) [5] , feedback linearization  ...

Linear predictors for nonlinear dynamical systems: Koopman operator meets model predictive control

Milan Korda, Igor Mezić
2018 Automatica  
We focus in particular on model predictive control (MPC) and show that MPC controllers designed in this way enjoy computational complexity of the underlying optimization problem comparable to that of MPC  ...  This paper presents a class of linear predictors for nonlinear controlled dynamical systems.  ...  By a predictor, we mean an artificial dynamical system that can predict the future state of a given nonlinear dynamical system based on the measurement of the current state and current and future inputs  ...
