Smart control system

Improve integration of boiler systems with the rest of the plant process with new "smart" control systems and designs that capture unused waste heat. 

Extremely precise engineering and coordination are necessary for the installation of instrumentation and wiring. Smart control systems coupled with communication systems are extremely critical for O M of the facilities. 

Such a model can be developed to a new design to get a feedback (FB) and build up a quality control system for materials. This scheme also includes smart block (SB) for optimal control and generation of a feedback function (Figure 1). 

Figure 8-62 depicts a hypothetical distributed control system. A number of different unit configurations are illustrated. This system consists of many commonly used DCS components, including multiplexers (MUXs), single/multiple-loop controllers, programmable logic controllers (PLCs), and smart devices. A typical system includes the following elements as well ...

The pole placement design predicates on the feedback of all the state variables x (Fig. 9.1). Under many circumstances, this may not be true. We have to estimate unmeasureable state variables or signals that are too noisy to be measured accurately. One approach to work around this problem is to estimate the state vector with a model. The algorithm that performs this estimation is called the state observer or the state estimator. The estimated state X is then used as the feedback signal in a control system (Fig. 9.3). A full-order state observer estimates all the states even when some of them are measured. A reduced-order observer does the smart thing and skip these measurable states. 

Since the development of Stage II-screening reactor systems in 1998 [71], the 48-fold reactor technology is, in the meantime, a state-of-the-art methodology in the context of robustness, cost, and efficiency, and operates 24 h a day, 7 days a week, which is eased by the use of a smart control...

In summary an FDEMS sensor system can be used to monitor the processing properties in situ during the fabrication process of a composite part. A smart sensor control system can be used to monitor resin properties for reproducability-quality assurance, to ensure fabric impregnation, and to control and optimize the composite fabrication process intelligently through in situ sensor feedback.

For electronic loops, check polarities, measure the loop impedance, and make the necessary compensating adjustments. The compensating adjustments on smart instruments can be made using either a handheld terminal or direcdy at the instrument. Smart instruments, if supported, can also be adjusted using an instrument configuration page on a computerized control system.
