From 2004 through to 2019, Coriolis Systems was a software company that supplied Mac utility software, including its award-winning iPartition partitioning tool and iDefrag disk optimizer, as well as a handful of other products including VMOptimizer, Zipster and a real time AC-3 compatible encoder, Aura. This used to be its website.
Used for slow processes (e.g., reactor temperature). An inner "slave" loop (flow) responds faster than an outer "master" loop (temperature). This isolates disturbances before they propagate.
Keywords: Control Loop Foundation, Batch Processes, Continuous Processes, PID Control, Process Automation, PDF Resource Introduction In the world of industrial automation, the difference between a well-tuned operation and a chaotic one lies in one critical concept: the control loop . Whether you are managing a refinery running 24/7 or a pharmaceutical bioreactor producing a single batch per day, understanding the foundational principles of control loops is non-negotiable. control loop foundation batch and continuous processes pdf

Disclaimer: Always follow site-specific safety procedures and plant standards before tuning controllers or modifying logic in live processes. Used for slow processes (e
Instead of modulating a valve continuously, you cycle a valve on/off. The ratio of on-time to off-time (duty cycle) determines the average energy input. Common for electric heaters in batch jacketed reactors. Keep it with your field tools
A disturbance is measured before it affects the PV. For example, measuring a change in inlet flow to a heat exchanger and pre-adjusting the steam valve. Combining feedback + feedforward is the gold standard for continuous processes.
More advanced than gain scheduling. The controller continuously re-identifies process dynamics and adjusts its own parameters in real-time. This is used for highly non-linear batch reactions (e.g., polymerization).
