Tahere Binazadeh; Mohammad Hossein Shafiei; Elham Bazregarzadeh

Volume 8, Issue 1 , April 2015, Pages 1-7

Abstract
  This paper presents a novel approach in design of missile guidance law against highly maneuvering targets. This approach is based on the principles of partial stability and finite-time stability (finite-time partial stability). Also, it is shown that the designed guidance law is in conformity with a ...  Read More

Numerical Investigation of Laminar Premixed Conical Flame Response to Acoustic Excitation

Milad Behzadi; Mohammad Farshchi

Volume 8, Issue 1 , April 2015, Pages 9-18

Abstract
  Dynamics of laminar premixed conical flame in acoustic-velocity field was studied via numerical simulation. Methane/air combustion was modeled using a single-step, irreversible reaction and diffusion phenomena with a simple but efficient method. First, the steady flame was obtained and its corresponding ...  Read More

Optimal Control of a Flexible Spacecraft in a Proximity Operation Using State Dependent Riccati Equation Approach

Mohammad Reza Mortazavi; Ali Reza Alikhani

Volume 8, Issue 1 , April 2015, Pages 27-41

Abstract
  This paper presents a suitable technique for nonlinear control of a flexible spacecraft in proximity operations. To do proximity operations well, the pursuer spacecraft must place itself in a pre specified location relative to target and align its docking port to target’s docking port while keeping ...  Read More

Active Control of a Smart Satellite under Thermal Loading

Emad Azadi; Seyed Ahmad Fazelzadeh; Mohammad Azadi

Volume 8, Issue 1 , April 2015, Pages 43-51

Abstract
  In this paper, vibration suppression and maneuver control of a smart flexible satellite moving in acircular orbit are studied. The satellite is considered as a rigid hub and two flexible appendages withpiezoelectric layersattached on them as actuators. The satellite is moving in a circular orbit and ...  Read More
