A Stability-constrained Optimization Framework for Lur'e Systems with Applications in Power Grids
Qifeng Li, Qiushi Wang, Konstantin Turitsyn
For many nonlinear control systems, the chosen equilibrium determines both the steady-state efficiency and the dynamic performance. This paper addresses the issue of obtaining an o…
