Effects of Discretization Methods on the Performance of Resonant Controllers
IEEE Transactions on Power Electronics, 2010Resonant controllers have gained significant importance in recent years in multiple applications. Because of their high selectivity, their performance is very dependent on the accuracy of the resonant frequency. An exhaustive study about different discrete-time implementations is contributed in this paper.

Performance Analysis of Concurrency Control Methods
2000Since the appearance of the first papers in mid-70’s formalizing two-phase locking as a means of Concurrency Control (CC) [23], there have been numerous proposals based on locking, time-stamp ordering, and optimistic CC [6], [52], [77]. CC is required to ensure correctness and database integrity when it is updated by several transactions concurrently ...

Evaluation of control performance: methods and applications
Proceedings of the International Conference on Control Applications, 2003Evaluating control performance has attracted considerable interest in recent years. A set of performance indices appropriate to process monitoring and assessment is presented and discussed in this paper. A graphical, user-friendly and interpretable program to display performance indices for operators is under development.

A high performance MPPT control method
2011 International Conference on Materials for Renewable Energy & Environment, 2011This paper presents the analysis, design and implementation of a high-performance step-up Maximum power point tracking (MPPT) system for grid-connected Photovoltaic (PV) generation. The high-achieved MPPT control method, which is an important essential part of the efficient and low-cost PV system, needs to solve two main problems: wrongly tracking the ...

A performance evaluation framework for network admission control methods
2004 IEEE/IFIP Network Operations and Management Symposium (IEEE Cat. No.04CH37507), 2004We introduce the notion of link and network admission control (LAC, NAC) and present three fundamentally different budget based NAC methods which categorize most of today's implemented NAC approaches. We propose a performance evaluation framework for their comparison.

Decentralized controllers design for performance: Equivalent Subsystems Method
2009 European Control Conference (ECC), 2009A Nyquist-based frequency domain decentralized controller (DC) design technique for stability and guaranteed performance is proposed applicable for continuous-time systems described transfer function matrices. To guarantee stability and a required performance, interactions are included in individual designs using one selected characteristic locus of ...

Instantaneous performance display for graphical control design methods
IFAC Proceedings Volumes, 1999Abstract Designing a controller usually involves several iterations between the synthesis based on a set of parameters, the analysis of the robustness and performance obtained so far, and correction of the design parameters. An approach based on Computer-Aided Design is proposed, where the engineer manipulates the graphics with a mouse, sees ...

Improving methods for control of logistics performance
2020IV ABSTRACT Due to lack of professionalism on logistics management, logistics costs usually exceed the budget. Also lack of statistical studies might be one reason for unsuccessful management of logistics activities. In need of a statistical approach, we develop a method to fill the gap in logistics sector.
