AXY:Element Synchronization/Design

Element Synchronization Design

Common algorithms to both SyncStart and SyncAll:

• 

  SyncStart Object model

• 

  SyncStart Class model

Pre-Calculation

Is done in MotionManager task, initiated by message sent from SyncStart/All commands:

In case of SyncStart we sperately execute MotCalc on every element from the sync-list:

FOR element FROM sync-list
   element->MotCalc()
NEXT

In case of SyncAll it is little bit more complicated, every element is pre-calculated in order to estimate it's own max profile values:

FOR element FROM sync-list
element->MotCalc() ==> L_i , V_i , A_i , D_i , Ja_i , Jd_i
NEXT

And then generate a master profile with the following parameters:

The master profile data-structure will be copied to the profile-data-structure of all other elements.

Master profile:

$L$ , $min(V_{i}\cdot {\frac {L}{L_{i}}})$ , $min(A_{i}\cdot {\frac {L}{L_{i}}})$ , $min(D_{i}\cdot {\frac {L}{L_{i}}})$ , $min(Ja_{i}\cdot {\frac {L}{L_{i}}})$ , $min(Jd_{i}\cdot {\frac {L}{L_{i}}})$

The master profile data-structure will be copied to the profile-data-structure of all other elements.

The complete system of the sync-list motion profiles will be executed together just be scaling each of them by the factor of:${\frac {L_{i}}{\sqrt {\sum L_{i}^{2}}}}$
