Cascade Control: Data-Driven Tuning Approach Based on Bayesian Optimization
Mohammad Khosravi, Varsha Behrunani, Roy S. Smith +2
Cascaded controller tuning is a multi-step iterative procedure that needs to be performed routinely upon maintenance and modification of mechanical systems. An automated data-drive…
Distributed Control Design for Heterogeneous Interconnected Systems
Yvonne R. Stürz, Annika Eichler, Roy S. Smith
This paper presents scalable controller synthesis methods for heterogeneous and partially heterogeneous systems. First, heterogeneous systems composed of different subsystems that…
Convex Nonparametric Formulation for Identification of Gradient Flows
Mohammad Khosravi, Roy S. Smith
In this paper, we develop a nonparametric system identification method for the nonlinear gradient-flow dynamics. In these systems, the vector field is the gradient field of a poten…
Nonlinear System Identification with Prior Knowledge of the Region of Attraction
Mohammad Khosravi, Roy S. Smith
We consider the problem of nonlinear system identification when prior knowledge is available on the region of attraction (ROA) of an equilibrium point. We propose an identification…
Stochasticity in Feedback Loops; Great Expectations and Guaranteed Ruin
Roy S. Smith, Bassam Bamieh
Stochastic feedback systems give rise to a variety of notions of stability. The conditions for the stability of the median, mean, and variance stability conditions differ. These co…
Robust Adaptive Model Predictive Control with Worst-Case Cost
Anilkumar Parsi, Andrea Iannelli, Mingzhou Yin +2
A robust adaptive model predictive control (MPC) algorithm is presented for linear, time invariant systems with unknown dynamics and subject to bounded measurement noise. The syste…
