LPV Robust Controller Design with Regional Pole Assignment for an Aero-Engine
Xibei Gongye Daxue Xuebao, 2019 The aerodynamic characteristics of aero-engine, which have a wide range of flight envelopes, vary drastically, so its controller is required to be able to adapt to a large range of parameter variations and have good robustness. To solve the above problem,

A state space approach to the problem of adaptive pole assignment [PDF]
Mathematics of Control, Signals, and Systems, 1989 Algorithms for adaptive pole assignment for a class of single- input/single-output linear systems are proposed. Pole-zero cancellation of the estimates is avoided by introducing a finite number of special inputs. A weak form of self-tuning is derived without imposing conditions on the richness of the signals. It is shown that the asymptotic behavior of

Weak regularizability and pole assignment for non-square linear systems [PDF]
, 2012 summary:The problem of pole assignment by state feedback in the class of non-square linear systems is considered in the paper. It is shown that the problem is solvable under the assumption of weak regularizability, a newly introduced concept that can be ...

Energies, 2019 In order to improve the dynamics of the surface-mounted permanent magnet synchronous motors (SPMSM) used in servo systems, finite control set model predictive current control (FCS-MPCC) methods have been widely adopted. However, because the FCS-MPCC is a

Historical Foundation and Practical Guideline for Ferroelectric Switching Kinetic Studies
Advanced Functional Materials, EarlyView.The P and U pulses in the conventional PUND measurements are not identical because of the interplay between switching current and the measurement circuit components. This circuit effect can lead to a shift in polarization transients and misinterpreted physics in the switching kinetics.

On minimal degree simultaneous pole assignment problems
Linear Algebra and its Applications, 2002 The main objective of this paper is to find the smallest possible integer \(q\) such that the closed-loop characteristic polynomials of a generic \(r\)-tuple of linear systems of degrees \(n_1,\dots, n_r\), respectively, can be arbitrarily assigned by a single dynamic compensator of degree not exceeding \(q\).

Advanced Materials, EarlyView.We introduce a molecular strategy to assemble one‐dimensional (1D) materials into two‐dimensional (2D) van der Waals metal–organic frameworks (MOFs). Crystals of [FeX(pzX)(bpy)] (X = Cl, F) form anisotropic 2D layers that can be mechanically exfoliated into thin sheets.

CONDITIONING OF STATE FEEDBACK POLE ASSIGNMENT PROBLEMS
Taiwanese Journal of Mathematics, 2012 In [26,27,35], condition numbers and perturbation bounds were produced for the state feedback pole assignment problem (SFPAP), for the single- and multi-input cases with simple closed-loop eigenvalues. In this paper, we consider the same problem in a different approach with weaker assumptions, producing simpler condition numbers and perturbation ...

In Situ Regenerative Adduct Assisted p‐Type Doping of Organic Semiconductor
Advanced Materials, EarlyView.An in situ regenerative adduct‐assisted (IRAA) doping strategy is introduced for p‐type doping of organic semiconductors. A regenerating adduct serves as the dopant, enabling highly efficient doping with a choice of counterions. The generality of this approach provides a scalable route to dope a wide range of hole‐transport materials with high thermal ...
