PID Controllers

Toshiba India has introduced Model Driven PID (MD-PID), a solution to energy and cost saving for long dead time control loops. E.g. in a coal fired boiler, these could be attained by stabilizing and increasing the main steam temperature within the operation range. MD-PID is a software function block (type of Internal Model Control algorithm) developed by Toshiba, which can be used with nvcontroller (DCS) and even with LC53X loop controller. The MD-PID can be optimized for not only set point (SV) change but also the process disturbance (DV).
