The impact of installing process control systems can be expected in terms of performance improvements through reduced operating costs.  Since these installations impose considerable capital expenditure, the profitability of the new systems should be economically justified. Controlled variable trend was reconstructed by a combination of simple waves, which provided a means to simulate the ef...

This paper purposed a new generalized predictive control based on state feedback theory for the large inertia and large delay characteristics of the discrete reheat steam temperature plant. The idea is to compensate the large inertia and delay characteristics of the plant by the state feedback theory and the generalized plant by predictive control. The simulation results show that that the new ...

Understanding how different units of an industrial production plant are operationally related is key to improving quality and sustainability. Data science has proven indispensable in obtaining such understanding from vast amounts historical process data. Path modelling a valuable statistical tool obtain information Investigating relationships within affected by multiple conditions their interac...

multivariate process capability indices (mpci) show how well a manufacturing process can meet specifica-tion limits when quality characteristics enclose a relative correlation. process capability is an important and commonly used metric for assessing and improving the quality of a production process. when quality charac-teristics of a product are correlated then an attractive comes close to mpc...

The phytochrome-mediated attachment of mung bean (Phaseolus vulgaris L., var. Oklahoma 612) root tips on glass is quickly affected by indoleactic acid and abscisic acid at concentrations of 10 nm or less. Indoleacetic acid induces detachment, whereas abscisic acid induces attachment. Both plant regulators rapidly antagonize the action of the other. None of several cytokinins, gibberellins, and ...

A methodology for the design of fault-tolerant control systems for chemical plants with distributed interconnected processing units is presented. Bringing together tools from Lyapunov-based nonlinear control and hybrid systems theory, the approach is based on a hierarchical architecture that integrates lower-level feedback control of the individual units with upper-level logic-based supervisory...

Faults in automated processes will often cause undesired reactions and shut-down of a controlled plant, and the consequences could be damage to technical parts of the plant, to personnel or the environment.Faulttolerant control combines diagnosis with control methods to handle faults in an intelligent way. The aim is to prevent that simple faults develop into serious failure and hence increase ...

To assist in the absorption of renewable energy, coal-fired power plants need to operate over a wide range loads, which exacerbates challenge time delay wet desulphurization process. Therefore, this paper proposes new control structure based on frequency retrofit and corresponding model predictive controller change traditional idea control. This provides faster actions, thus reducing directly. ...

Agrobacterium-mediated transient expression systems enable plants to produce a wide range of recombinant proteins on a rapid timescale. To achieve economically feasible upstream production and downstream processing, two yield parameters should be considered: (1) recombinant protein content per unit biomass and (2) recombinant protein productivity per unit area-time at the end of the upstream pr...

The synthesis and optimization of plant-wide waste management policies under uncertainty is the subject of this paper. The combinatorial synthesis methodology (Chakraborty, A.; Linninger, A. A. Ind. Eng. Chem. Res. 2002, 41 (18), 4591-4604) was adapted to incorporate variations in the expected waste loads. In its first stage, automatic generation of recovery and treatment flowsheet produces a s...
