Minimize waste of material and maximize quality of product by maintaining tight, responsive control of the interaction of the parameters of temperature, pressure, pH, and dissolved oxygen (DO2), which enables both anaerobes and organisms requiring high oxygen input to be grown.
ControlSoft's MANTRA's Coordinated Control (CC) function block is used to control dissolved oxygen content to desired levels. The goal of the CC block is three-fold: reject any disturbances to the process, respond quickly to setpoint changes, and optimize the available controller outputs during steady-state control.

Extrusion Barrel Temperature control is one of the most difficult and commonly seen control problems. In the heating cycle, for example, both heating power and time are required to heat the system. Once the temperature starts to rise, it will increase slowly but steadily, and will tend to continue to increase for some time, even after the heating device has been turned off. Hence, one often ends up with a large overshoot and oscillatory response (with a very long cycle time).
A specially designed control strategy is incorporated in ControlSoft's MANTRA Temperature Control Module (TCM) such that each stage of the control is treated differently, since different requirements are imposed at different stages, such as tuning stages, start-up stage, initial control stage, and run-time production control. With the use of TCM, all these internal stages are transparent to users. After configuring the TCM block, only one start button is required for a user to commission TCM control.
Key Advantages of the ControlSoft TCM Technology over Traditional PID Controllers:

Multiple Scraped Surface Heat Exchangers (SSHE) are typically connected in series to heat various products. With traditional PID control, the temperature fluctuations in a previous SSHE will affect the next SSHE, with some time delay and lag. If one SSHE temperature is oscillating, for any SSHE that follows the temperatures will oscillate propagating through the entire system. Also the product flow speed changes cause the control dynamics to be non-linear.

ControlSoft's MANTRA Advanced Process Control Software (APC) is designed to handle the most difficult moisture control situations, such as
ControlSoft's application note, AN314, uses the example of a multiple-zone oven to show how decoupling the variables in the control loop can compensate for interactions that produce errors. The implemented Coordinated Controller (CC) block rejects any disturbances to the process and optimizes the controller outputs during steady state control. AN314 also includes a block diagram showing how a simplified moisture control strategy is implemented in Mantra Advanced Process Control software.
ControlSoft's solutions featuring MANTRA APC technology can increase the profitability of your process with no replacement of existing hardware or wiring required.
