Application of systems identification techniques to a superheater simulator using MATLAB

The CEGB has devised a distributed computer installation consisting of a host machine and three target machines. One target controls five real and simulated plant systems via a suitable interface. The five plants have been selected to demonstrate different aspects of control such as three-element, cascade and ratio. The plant was designed as scaled down versions of boiler drums, temperature controllers, pressure systems, etc., and has been constructed as working engineering systems using hardware such as motors, valves, water tanks and pipework. Each physical plant system may be controlled by a target computer running CUTLASS software schemes. In order to give more of the CEGB trainee engineers hands on experience of real-time control using CUTLASS, the development of a low cost version of the power plant simulator was proposed. The low cost simulator is able to simulate any of the original sections of plant, or several sections simultaneously by using a dedicated microprocessor
