Discrete-time sliding mode control of high precision linear drive using frictional model [PDF]
, 2006 The paper deals with high precision motion control of linear drive system. The accuracy and behavior of the linear drive system are highly affected by the non-linear frictional component compromising of stiction, viscous and stribeck effect present in ...

AIMS Mathematics, 2022 This work develops some novel approaches to investigate the stability analysis issue of linear systems with time-varying delays. Compared with the existing results, we give three innovation points which can lead to less conservative stability results ...

Linear and Branching System Metrics [PDF]
, 2009 We extend the classical system relations of trace\ud inclusion, trace equivalence, simulation, and bisimulation to a quantitative setting in which propositions are interpreted not as boolean values, but as elements of arbitrary metric spaces.\ud \ud ...

FEEDBACK LINEARIZATION OF PIECEWISE LINEAR SYSTEMS [PDF]
IFAC Proceedings Volumes, 2005 One of the classical problems of nonlinear systems and control theory is feedback linearization. Its obvious motivation is that one can utilize linear control theory if the nonlinear system at hand is linearizable by feedback. This problem is well-understood for the smooth nonlinear systems. In the present paper, we investigate feedback linearizability

IEEE Access, 2019 The tumor microenvironment associated with deficiencies in nutrients and oxygen is important in observing the regulation of tumor progression. The aggressiveness of the tumor cells can be stimulated by exposing it to nutrient starvation and hypoxia ...

Linear active disturbance rejection control of waste heat recovery systems with organic Rankine cycles [PDF]
, 2012 In this paper, a linear active disturbance rejection controller is proposed for a waste heat recovery system using an organic Rankine cycle process, whose model is obtained by applying the system identification technique.

Journal of Differential Equations, 1989 The authors deal with perturbations of stable linear differential or integrodifferential systems in abstract spaces analysing the robustness of the stability. For systems governed by semigroups or resolvent operators they characterize the robustness in terms of stability radii.

Penalization for non-linear hyperbolic system [PDF]
, 2013 This paper proposes a volumetric penalty method to simulate the boundary conditions for a non-linear hyperbolic problem. The boundary conditions are assumed to be maximally strictly dissipative on a non-characteristic boundary.

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada
Population Ecology, EarlyView.We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...

Initial algebra for a system of right-linear functors [PDF]
, 2017 In 2003 we showed that right-linear systems of equations over regular expressions, when interpreted in a category of trees, have a solution when ever they enjoy a specific property that we called hierarchicity and that is instrumental to avoid critical ...
