1. Workspace Analysis of 2-PR(Pa)U- 2-PR(Pa)R New Parallel Mechanism

Mehran Mahboubkhah; Sajjad Pakzad

Volume 10, Issue 4 , December 2017, Pages 1-6

  Parallel kinematic machines, are closed loop structures which have more accuracy, stiffness and ability to withstand high loads. Kinematic of these mechanisms is complicated due to their closed–loop structure, parallel pods, joint constraints and movement constraints. This paper proposes a new ...  Read More

2. Fuzzy-GSA Based Control Approach for Developing Adaptive Cruise Control

M. Bostanian

Volume 10, Issue 4 , December 2017, Pages 7-19

  Adaptive Cruise Control (ACC) controls vehicle speed and its distance to the proceeding vehicle in the same lane. In this paper a two-level control architecture is proposed to control both velocity and distance to the leading vehicle by taking advantage of fuzzy logic control (FLC) approach. Then the ...  Read More
