This paper presents an Kalman Filter Data Fusion methodology and investigation for high dynamics and high precision multi-head angular position encoder. The proposed algorithm based on measurement of four dependent Read Heads and encoder ring for one mechanical shaft of high precision system with electric drive. The global fusion of proposed estimation provide computed value of position and additional...
Permanent magnet track linear motor drives are used in numerous industrial manufacturing processes covering a wide range of material handling and conveyor applications. A traditional solution is a permanent magnet linear motor (PMLM) in which the stationary part consists of permanent magnets and the moving part of the armature. To further reduce the initial costs of such a permanent magnet track linear...
This paper presents an estimation procedure of equivalent electric circuit parameters of a lithium-ion cell using data from a pulse charge/discharge test. An extraction process of the model parameters is based on a transient voltage response of relaxation process following a current pulse. The entire procedure is straightforward and there is no restriction in a number of parallel RC-branches in the...
Stepping motors are well suited for open-loop positioning tasks at low-power. The rotor position of the machine can simply be controlled by the user. Every time a next pulse is sent by the user, the stepping motor driver excites the correct stator phases to rotate the rotor over a pre-defined discrete angular position. In this way, counting the step command pulses enables open-loop positioning. However,...
