Plant-Wide Control Design Based on Steady-State Combined Indexes

  Abstract: This work proposes an alternative methodology for designing multi-loop control structures based on steady-state indexes and multi-objective combinatorial optimization problems. Indeed, the simultaneous selection of the controlled variables, manipulated variables, input-output pairing, and controller size and interaction degree is performed by using a combined index which relies on the sum of square deviations and […]

Measuring Fuel Oil Viscosity in a Power Plant

  Abstract: The viscosity measurement and control of fuel oil in power plants is very important for a proper combustion. However, the conventional viscometers are only reliable for a short period of time. This paper proposes an on-line analytic viscosity evaluation based on energy balance applied to a piece of tube entering the fuel oil main […]

Auto-Tuning Method for Fractional Order PID Controllers

  Abstract: Fractional order PID controllers benefit from an increasing amount of interest from the research community due to their proven advantages. The classical tuning approach for these controllers is based on specifying a certain gain crossover frequency, a phase margin and a robustness to gain variations. To tune the fractional order controllers, the modulus, phase […]

How to Monitor and Control Quality in Process Manufacturing

  In nearly all regions and industries, markets for products reflect the impact of globalization. The tactic of competing on price is increasingly giving way to a wider range of factors—including product quality. The idea of improving the quality attributes of products is not new, but it has become far more scientific in its approach. […]

How to Reduce Diesel Engine Pollution Through a High-Pressure Common Rail Injection System

  Abstract: In this paper, modeling and common-rail pressure control of high-pressure common rail injection system (HPCRIS) is presented. The proposed mathematical model of high pressure common rail injection system which contains three sub-systems: high pressure pump sub-model, common rail sub-model and injector sub-model is a relative complicated nonlinear system. The mathematical model is validated by […]
