## Question

What are the benefits of computer based control implementation?

## Short answer

Computer-based control provides flexibility via software, accuracy without drift, ability to implement advanced algorithms and filtering, integration of multiple loops with logging and networking, and lower cost and size with built-in diagnostics.

## Answer

- **Flexibility:** the controller is software, so algorithm and gains can be changed without hardware changes.
- **Accuracy and repeatability:** no drift or ageing of analog components; results are identical on every unit.
- **Advanced control:** non-linear, adaptive, multivariable control and filtering are easy to implement.
- **Integration:** one processor can run several loops and also logging, display, alarms and networking.
- **Lower cost and size** than equivalent analog circuits, with built-in monitoring and diagnostics.
