  1. Process variability: Process variability can make it difficult to design and tune control loops.
  2. Non-linearity: Non-linear processes can make it challenging to design and tune control loops.
  3. Interactions between loops: Interactions between control loops can make it difficult to design and tune control loops.

3. The Batch Process Foundation

The second major section addresses Batch control, governed largely by the ISA-88 (IEC 61512) Standard. This is where the literature distinguishes itself from general control theory. Process variability : Process variability can make it

  1. Temperature control loops: Temperature is a critical parameter in batch processes, and temperature control loops are used to regulate the temperature of reactors, mixers, and other equipment.
  2. Pressure control loops: Pressure control loops are used to regulate the pressure of vessels, tanks, and pipes in batch processes.
  3. Flow rate control loops: Flow rate control loops are used to regulate the flow rate of materials in batch processes.

3.4 Sequence Control Integration

Batch loops do not operate in isolation. They are coordinated by a Sequential Function Chart (SFC) or similar state machine. The same temperature loop has different tuning parameters and different output limits depending on the phase.

Part 1: The Universal Foundation – What is a Control Loop?

Before differentiating between process types, one must understand the basic control loop. Regardless of the industry (pharmaceuticals, oil & gas, food production), every control loop consists of four core components:
