POLYNOMIAL LPV SYNTHESIS APPLIED TO TURBOFAN ENGINES [PDF]
IFAC Proceedings Volumes, 2007 Abstract Results on polynomial fixed-order controller design are extended to SISO gain-scheduling with guaranteed stability and H ∞ performance over the whole scheduling parameter range. Salient features of the approach are: (a) the use of polynomials as modeling objects; (b) the use of flexible linear matrix inequalities (LMI ...

Deep Reinforcement Learning‐Based Control for Real‐Time Hybrid Simulation of Civil Structures
International Journal of Robust and Nonlinear Control, EarlyView.ABSTRACT Real‐time Hybrid Simulation (RTHS) is a cyber‐physical technique that studies the dynamic behavior of a system by combining physical and numerical components that are coupled through a boundary condition enforcer. In structural engineering, the numerical components are subjected to environmental loads that become dynamic displacements of the ...
