Adaptive Damping Design of PMSG Integrated Power System with Virtual Synchronous Generator Control
Published 2020-04-01“…The active power of PMSG is selected as the variable parameter vector to establish a polytopic linear variable parameter system model. Then, based on the hybrid H<sub>2</sub>/H<sub>∞</sub> control method, each vertex state feedback matrix is solved by linear matrix inequality, and a subsynchronous oscillation adaptive damping controller with polytope is obtained. …”

Eradication Conditions of Infected Cell Populations in the 7-Order HIV Model with Viral Mutations and Related Results
Published 2021-08-01“…We compute ultimate upper bounds for all model variables that define a polytope containing the attracting set. The theoretical possibility of eradicating HIV-infected populations has been investigated in the case of a therapy aimed only at eliminating wild-type HIV particles. …”

Pricing Equilibria and Graphical Valuations
Published 2019“…Interestingly, by exploiting a novel connection between the existence of a pricing equilibrium and the partitioning polytope associated with the underlying graph, we also establish that for simple (series-parallel) value graphs, a pricing equilibrium with anonymous graphical pricing rule exists if and only if a Walrasian equilibrium exists. …”

Learning via automaton minimization and matrix factorization
Published 2016“…We first tackle a variant of the problem, restricted NMF, which has applications in topic modelling and a geometric interpretation as the nested polytope problem. Lastly we show that NMF is polynomial-time reducible to automaton minimization, and then use our results on NMF to answer old open problems on minimizing labelled Markov chains and probabilistic automata.…”

Reduction of Low Frequency Oscillations Using an Enhanced Power System Stabilizer via Linear Parameter Varying Approach
Published 2022-04-01“…To guarantee the flexibility of the stabilizer with respect to the aforementioned issues, the power system polytopic representation is used. In order to apply the new method, the nonlinear equations of the system at each operating point, located in a polytope, are parametrically linearized by scheduling variables. …”

Costly circuits, submodular schedules and approximate Carathéodory Theorems
Published 2018“…Seen alternatively, the algorithm provides a fast and approximate solution toward a constructive version of Carathéodory’s Theorem for the Birkhoff polytope. The algorithm also has strong connections to submodular optimization, achieves a performance at least half that of the optimal schedule and strictly outperforms the state of the art in a variety of traffic demand settings. …”

A Generalized Fault Coverage Model for Linear Time-Invariant Systems
Published 2010“…These performance requirements constrain the system trajectories to some region of the state-space defined by a symmetrical polytope. When a fault occurs, the state-transition matrix, and the input matrix might be altered; and then, it is guaranteed the system survives the fault if all possible post-fault trajectories are fully contained in the region of the state-space defined by the performance requirements. …”

Anisotropic geometry-conforming d-simplicial meshing via isometric embeddings
Published 2018“…In particular, we compute restricted Voronoi simplices using exact arithmetic and use data structures based on convex polytope theory. Finally, since adaptive solvers require geometry-conforming meshes, we offer a Steiner vertex insertion algorithm for ensuring the extracted dual Delaunay triangulation is homeomorphic to the input geometries. …”
