Abstract

The first process control systems used mechanical and pneumatic controllers. Ever since then, the process control sector has seen numerous developments; amongst them is the foundation fieldbus technology. Fieldbus has been around for sometime, but not until recently has it caught the attention of users and manufacturers alike. Fieldbus claims to require less hardware, have easy installation and commissioning, provide good data both in quality and quantity, need easy and simple maintenance and be interoperable with other devices. This project aims to prove those claims. A foundation fieldbus test platformwill be designed and built. This test platform will include a simple control loop with fieldbus transmitters, gauges and control valves. A control strategy of cascade control and PID control will be used. Influenced by the safety system of a plant, the test platform is designed to emulate part of the fire water pump system. When there is a leak in the fire water pipes, the drop in pressure inside the pipes will trigger the system to pump in more water. The first part of this project will cover the research and design stages. Thorough research on the fieldbus technology, different control strategies and installation and commissioning is needed for the success ofthe second part of the project. Once the design has been finalized, and deemed feasible, the test platform will be built. Tests, troubleshooting and maintenance will follow. In the light of further improving this project, state-space mode can be used as an alternative control strategy. It should provide greater performance, increased stability and controllability. Fieldbus has the potential of being the best, with its extra features, such as diagnostics and predictive maintenance. Digital control is the thing ofthe future.
