MANTRA's Coordinated Control (CC) function block is a predictive
model-based controller that decouples the interaction of multiple manipulated
variables with a single process variable. This advanced function block
is used singularly or in multiples to optimize the burning of multiple
fuels or to optimize the allocation of multiple boilers.
The goal of the CC block is two-fold: reject any disturbances to the
process and optimize the controller outputs during long-term steady state
- Implemented with a multiple-fuel boiler the CC block maximizes
the burning of lower cost fuel while maintaining the boiler performance
and efficiency. Fuel rates react dynamically to maintain the boiler
performance targets through disturbances. When performance is at steady
state, the CC block optimizes the use of lower cost fuels without disturbing
- Implemented with multiple boilers the
CC block allocates the total plant steam demand between the various
boilers based on minimum costs while observing boiler constraints.
Boiler load allocation reacts dynamically to meet the total demand.
When the plant demand has reached steady state, the CC block optimizes
the boiler allocation without disturbance to the plant system.
MANTRA Advanced Control System can be applied on your existing control
system and HMI, minimizing engineering and eliminating operator training.
