Analysis of discrete time schemes for milling forces control under fractional order holds [PDF]

, 2013
In this paper, discrete time model reference control schemes for practical milling using different discretization of the continuous-time plant are presented. First, a basic controller scheme is addressed where a fractional order hold with pre-fixed value

Optimizing Strategies for Non‐Invasive Prospection of Settlements in the Intertidal Zone: A Case Study From the Centre of the Drowned Medieval Village of Tolsende (Scheldt Estuary, the Netherlands)

Archaeological Prospection, EarlyView.
ABSTRACT Medieval and early modern drowned villages in the intertidal zone of the Scheldt estuary (the Netherlands) constitute intriguing yet largely understudied components of north‐western Europe's underwater cultural heritage. Despite their high archaeological potential as time capsules of past settlement landscapes, research has remained limited ...

Synchronization between Fractional-Order and Integer-Order Hyperchaotic Systems via Sliding Mode Controller

Journal of Applied Mathematics, 2013
The synchronization between fractional-order hyperchaotic systems and integer-order hyperchaotic systems via sliding mode controller is investigated. By designing an active sliding mode controller and choosing proper control parameters, the drive and ...

Circular Economy in Crisis Contexts: An Assessment Framework for Post‐Disaster Building Stock Toward Strategic Autonomy

Business Strategy and the Environment, EarlyView.
ABSTRACT Post‐disaster contexts generate large volumes of damaged building stock with significant, yet often unquantified, circularity potential. Through the lens of strategic management, the circular economy emerges as a transformative pathway to strengthen systemic resilience by reducing dependencies on external resources and mitigating supply chain ...

An Adaptive Tracking Control of Fractional-Order Chaotic Systems with Uncertain System Parameter [PDF]

, 2020
An adaptive tracking control scheme is presented for fractional-order chaotic systems with uncertain parameter. It is theoretically proved that this approach can make the uncertain parameter fractional-order chaotic system track any given reference ...

Study on a class of chaotic systems with fractional order

Acta Physica Sinica, 2008
In this paper, a class of chaotic systems with fractional order is generalized and their topological equivalence is proved. It indicates that the necessary condition for a system with fractional order to generate chaotic attractor is to maintain the stability of the equilibrium points of the system.

Assessment of Gibbs Free Energy Calculation in PI‐Controlled Heating

Chemie Ingenieur Technik, EarlyView.
For description and control of chemical processes in lab or industry thermodynamic variable Gibbs free energy provides opportunity to compare and interpret phenomena, even on a quantitative level. In a case study for PI‐controlled heating, impacts on its limits from control delay until parameter quantization are highlighted and assessed.

Comparison of modelling approaches for liquid fluidized beds

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study presents a comparison of three promising numerical models for the detailed simulation of liquid–solid fluidized bed. These models differ in their treatment of the solid phase, ranging from treating each particle individually to treating the collection of particles as a continuum.
