Decentralized control of linear switched systems with receding horizon
… for controller synthesis are obtained via Linear Matrix Inequalities (LMIs). Using known derivations for a centralized controller with look-ahead, we were able to extend the decentralized problem with finite memory to include receding horizon modal information. We then compare the …

Robust Control for Inter-area Oscillations
… on system stability, it is possible to use Linear Matrix Inequalities (LMIs) to design a multi-objective state feedback. The LMI optimization finds a control law that stabilizes several contingencies simultaneously using a polytopic model of the system. However, the number of cases to be …

Switched Markov Jump Linear Systems: Analysis and Control Synthesis
Markov jump linear systems find application in many areas including economics, fault-tolerant control, and networked control. Despite significant attention paid to Markov jump linear systems in the literature, few authors have investigated Markov jump linear systems with time-inhomogeneous Markov …

Feedback control design for closed-loop oscillations via dominant system theory
Stable oscillations, arising from nonlinear non-equilibrium dynamics, are an important class of behavior in both nature and engineering. For engineering applications like robotic locomotion, it is usually desirable to induce oscillations in a controlled manner. While plenty of feedback control …
