Process Control for Continuous Bioprocessing - BioProcess ...

May 15, 2020  For a batch process a process control strategy could be designed around a single unit operation. But for continuous systems, the control of one unit operation affects what happens in the next. So a greater level of understanding is needed about the interactions of different steps in a continuous process.

Why batch processes are difficult - Control Global

Jul 22, 2015  Batch process control can seem like another world compared to continuous process control. In batch operations, process conditions are constantly changing and control loops are going in and out of service. PID control may take a back seat to sequential scheduling of manipulated flows. Here we look at why batch processes are so different and challenging and what can we do wherever

Introduction to Process Control

CLASSIFICATION OF PROCESS CONTROL STRATEGIES •Method 1 is an example of a feedback control strategy. •The distinguishing feature of feedback control is that the controlled variable is measured, and that the measurement is used to adjust the manipulated variable. For feedback control, the disturbance variable is not measured.
