On Line Optimal Control of Robots for Tracking without Inverse Kinematics
(Revista Computación y Sistemas; Vol. 13 No. 2, 2009-10-15)
Abstract. This article presents a novel on-line optimal control for tracking tasks on robot manipulators for which inverse kinematics is not required. The controller is composed by a stabilization Cartesian PID control ...
Kinematic identification of parallel mechanisms by a divide and conquer strategy
(INSTICC-INST SYST TECHNOLOGIES INFORMATION CONTROL & COMMUNICATION, 2010-01-01)
This paper presents a Divide and Conquer strategy to estimate the kinematic parameters of parallel symmetrical mechanisms. The Divide and Conquer kinematic identification is designed and performed independently for each ...
Cluster space linear parameter varying control of robot formations
(Institute of Electrical and Electronics Engineers, 2018)
Within the Cluster Space robot formation control scheme, a new approach is presented where a cascaded control scheme is proposed. On one hand, a simple secondary (inner) loop is used to control the formation’s velocity in ...

Spectral analysis and low-frequency multipath mitigation for kinematic applications
(2008-11-10)
Low-frequency multipath is still one of the major challenges for high precision GPS relative positioning. In kinematic applications, mainly, due to geometry changes, the low-frequency multipath is difficult to be removed ...
