Abstract
  One of the current problems in the development of simulation software of flying objects is the process of software development and development from the concept design phase of a project to the final stages of the hardware in the loop. In this paper, the necessary software engineering standards and procedures ...  Read More

Flatness-based Near Optimal Guidance

Reza Esmaelzadeh; Abolghasem Naghash; mahdi mortazavi

Volume 10, Issue 3 , December 2017, , Pages 15-24

Abstract
  An optimal explicit guidance law that maximizes terminal velocity is developed for the reentry of a vehicle to a fixed target. The equations of motion are reduced with differential flatness approach and acceleration commands are related to the parameters of trajectory. An optimal trajectory is determined ...  Read More

Explicit Flatness-Based Guidance in Reentry Phase

R. Esmaelzadeh

Volume 6, Issue 4 , January 2014, , Pages 29-36

Abstract
  An explicit guidance law is developed for a reentry vehicle. Motion is constrained to a three-dimensional Bezier curve. Acceleration commands are derived by solving an inverse problem that combined with differential flatness approach. Trajectory is related to Bezier parameters. A comparison with pure ...  Read More
