-----------------------------------------------------------------
Conveyor Belts, only left to right, designed with hiosys-approach
-----------------------------------------------------------------
Controller design, physical interface and simulation model for the conveyor-belt chain "cb11-cb4-cb12-cb5-cb13-cb6-cb14-cb10" of the LRT Fischertechnik model.
E.g. for the first 4 conveyor belts, we obtain the following hierarchy of automata:
ABCD_controller
|
-------------------------------------
| |
AB_controller CD_controller
| |
-------------------- ------------------
| | | |
A_controller B_controller C_controller D_controller
| | | |
-------------------------------------------------------------------------
phys_interface(eg.'phys_A_l_implies_cb11-x-y.vio')
-------------------------------------------------------------------------
| | | | \
plant_cb11 plant_cb4 plant_cb12 plant_cb5 plant_TICK
The lowest level ("plant_") implements a timed physical model of the conveyor-belt chain.
The model 'plant_TICK' implements the passing of time for the controllers 'A_'
to 'D_'(20 time units per wait-loop). For HIL-Simulation, the "plant_" layer is replaced
by IO devices.
The physical interface translates physical sensor edges to abstract inputs for
the controllers 'A_' to 'D_', and translates abstract controller outputs to
physical actuator edges.
The folder data/5_conveyor_belts/hil_demo/ contains a script 'run.sh' and
appendage to run the controllers in HIL simulation with the lrtlab Fischertechnik model.
See data/5_conveyor_belts/hil_demo/README.txt for details. To update hil_demo
with the latest controllers computed by this tutorial, run
hio_5_conveyor_belts_update_hil_demo.sh
Note: execution of this tutorial can take about two hours!
