Split-Range Control in Process Systems

Slide Note

The concept of split-range control involves coordinating multiple actuators to adjust system parameters effectively. This course delves into the intricacies of utilizing different actuators, such as throttle and brake, in a coordinated manner to regulate processes. By manipulating control signals and employing one controller to govern various actuators, students gain insights into optimizing system performance through split-range control strategies.

Course: Process Control, NMBU Dec 2017 - April 2018 Split-range control By Finn Aakre Haugen, PhD, TechTeach (finnhaugen@hotmail.com) F. Haugen. Process Control. NMBU. 2018. 1

2 When you control the speed of your limousine: You have two actuators: The throttle and the break. Would you use both the throttle and the break, simultaneously, to adjust the speed, or would you use one of them at a time, i.e. use the actuators in a coordinated manner? This is what split-range control is about - namely, coordinated use of several actuators. F. Haugen. Process Control. NMBU. 2018. 2
