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:

SIMEQ SYSTEM:

Matlab basis software, see: http://www.mathworks.com/products/matlab/

Control System Toolbox see: http://www.mathworks.com/products/control/

System Identification Toolbox see: http://www.mathworks.com/products/sysid/

Model Predictive Control Toolbox see: http://www.mathworks.com/products/mpc/

Neural Network Toolbox see: http://www.mathworks.com/products/neuralnet/

Fuzzy Logic Toolbox see http://www.mathworks.com/products/fuzzylogic/

Optimization Toolbox see: http://www.mathworks.com/products/optimization/

 

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.
