Predictive control of switched nonlinear systems with scheduled mode transitions
TL;DR: The main idea is to design a Lyapunov-based predictive controller for each constituent mode in which the switched system operates and incorporate constraints in the predictive controller design which upon satisfaction ensure that the prescribed transitions between the modes occur in a way that guarantees stability of the switched closed-loop system.
Journal ArticleDOI
Stabilization of nonlinear systems with state and control constraints using Lyapunov-based predictive control☆
TL;DR: This work considers the problem of stabilization of nonlinear systems subject to state and control constraints and proposes a Lyapunov-based predictive control design that guarantees stabilization and state and input constraint satisfaction from an explicitly characterized set of initial conditions.
Journal ArticleDOI
Output feedback control of switched nonlinear systems using multiple Lyapunov functions
TL;DR: The switching logic tracks the evolution of the state estimates generated by the observers and orchestrates switching between the stability regions of the constituent modes in a way that guarantees asymptotic stability of the overall switched closed-loop system.
Journal ArticleDOI
Operational optimization and demand response of hybrid renewable energy systems
TL;DR: In this paper, a methodology to systematically formulate a hybrid renewable energy system (HRES), which consists of solar, wind and diesel generator as a backup resource as well as battery storage, from the preliminary design stage to the optimal operation is presented.
Book
Control of Nonlinear and Hybrid Process Systems: Designs for Uncertainty, Constraints and Time-Delays
TL;DR: In this paper, the authors present analysis and control of nonlinear systems with uncertainty and time delays, as well as fault tolerance and fault-tolerant control of process systems.
