Process
Control and Optimisation
The process control by
Simeq is based on the many tools in the Matlab Software from The MathWorks.
Matlab has for many years
been recognized as state of the art in control engineering and a full scale
SIMEQ system
will include some or all of the following:
For a full list of all
available toolboxes see: http://www.mathworks.com/products/product_listing/index.html
What tools to use
depends on the application and the process behaviour - often Matlab and the
Optimization toolbox is enough.
Standard
products in the Assistant series:
Blend
Assistant
– based on X-ray analyses of the raw materials calculates the new mixing
ratios to the feeders.
The control algorithm can be sample based PI dynamics or Model Predictive
Control. Both mixing/storage silos and continuous flow silos can be handled.
The mixing can be set to
optimize LSF, SIM and ALM or via
Bogue further to C3S, C2S, C3A and C4AF (if the necessary number of different
raw materials are available).
If kiln additive feeders are available,
fuels
not
chemical neutral can be compensated directly in kiln feed.
Vertical Mill Assistant – Control of vertical mill with gasflow
control and multivariable control of grinding situation.
Fineness control included. Also grinding economy optimization can be included
if different raw materials give
reason to different optimum operating conditions.
Kiln Assistant – Continuous combustion
calculation and heat balance. Multiple fuel control.
Multiple operator inserted constraints.
High kiln stability due to continuous control and automatic burning
value compensation.
See separate description.
Ball Mill
Assistant – Control
of mass flow, fineness and temperature control. Based on electronic ear, mill
main
motor kW, elevator kW and reject flow rate. Constant gasflow through separator
included.
Recipe system with unlimited number of recipes, allowing grinding economy
statistics to be made.
See separate description.
