Gholamreza Bidari; Naser Pariz; Ali Karimpour

Volume 2, Issue 1 , January 2019, Pages 1-6

https://doi.org/10.22111/ieco.2018.24693.1032

Abstract
  This paper investigates the stabilization problem of an autonomous Linear Time Invariant (LTI) switched system with interval uncertainty and unstable subsystems. It is proved that the system would be stable by using a common Lyapanov function whose derivative is negative and bounded by a quadratic function ...  Read More

Improvement of direct power control of DG-Interfaced grid connected Power Converter

Ehsan Talebian Kouchaksaraei; Mehrdad Ahmadi Kamarposhti

Volume 2, Issue 1 , January 2019, Pages 7-16

https://doi.org/10.22111/ieco.2018.25131.1039

Abstract
  Limitation of fossil fuel reserves and environmental pollution resulting from their use, especially in cities, as well as low efficiency of current energy converters lead to the tendency towards the use of more efficient energy converters and renewable energy sources. The use of distributed generation ...  Read More

Designing full-order sliding mode controller based on ANFIS approximator for uncertain nonlinear chaotic systems

Khadijeh Akbari; Behrooz Rezaie; Safa Khari

Volume 2, Issue 1 , January 2019, Pages 39-46

https://doi.org/10.22111/ieco.2018.23854.1003

Abstract
  In this paper, a full-order sliding mode controller, based on adaptive neuro-fuzzy inference system is proposed as approximator, for controlling nonlinear chaotic systems in presence of uncertainty. At first, the full-order sliding mode controller is designed for the system in the absence of uncertainty ...  Read More

A novel fast maximum power point tracking for a PV system using hybrid PSO-ANFIS algorithm under partial shading conditions

Javad Farzaneh; Reza Keypour; Ali Karsaz

Volume 2, Issue 1 , January 2019, Pages 47-58

https://doi.org/10.22111/ieco.2018.25721.1056

Abstract
  It is highly expected that partially shaded condition (PSC) occurs due to the moving clouds in a large photovoltaic (PV) generation system (PGS). Several peaks can be seen in the P-V curve of a PGS under such PSC which decreases the efficiency of conventional maximum power point tracking (MPPT) methods. ...  Read More

Dynamic Modelling and Optimal Control of a Rotor of Active Magnetic Bearings

Rohollah Dosthosseini; Nima Banisaeid; Asghar Dashti

Volume 2, Issue 1 , January 2019, Pages 59-70

https://doi.org/10.22111/ieco.2018.25595.1053

Abstract
  Active magnetic bearings (AMBs) are relatively new members in bearings family. Against other bearings which support loads by forces produced by fluid film pressure or physical contact, AMBs support loads by magnetic fields without any contact with the shaft and make it to be levitated. Because of that ...  Read More

Fractional sliding mode control design for robust synchronization and anti-synchronization of fractional order nonlinear chaotic systems in finite time

amin ramezani; Seyed Arash Pourhashemi Shahri; Mahdi Siahi

Volume 2, Issue 1 , January 2019, Pages 71-80

https://doi.org/10.22111/ieco.2018.25291.1045

Abstract
  This paper deals with the problem of synchronization (anti-synchronization) of fractional nonlinear systems. Here, due to the advantages of fractional calculus and sliding mode control, we provide a new fractional order sliding mode control for synchronization (anti-synchronization) problems. So, in ...  Read More
