Relay Autotuning of Multivariable Systems: Application to an Experimental Pilot-scale Distillation Column
نویسندگان
چکیده
This paper describes the application of multivariable sequential relay autotuning techniques to a pilot scale distillation system under industrial DCS monitoring and control environment. Implementation aspects arising in any realistic industrial environment are fully discussed such as the architecture for on-line communication and information extraction as well as valve hysteresis and backlash compensation. The performance of alternative tuning strategies is compared for both set-point changes and disturbances rejection. Copyright © 2002 IFAC

Extensions and Modifications of Relay Autotuning
In this thesis extensions and modifications of Åström-Hägglund autotuning are investigated. A method where relay autotuning is extended to multi-input-multi-output control systems is suggested. The method is based on identification of n×n simple two-parameter transfer functions through n identification experiments. The method is experimentally tested on a water-mixer and a pilot-plant distillat...
متن کاملOn-line Parameter Estimation and Control for a Pilot Scale Distillation Column
A dynamic model developed in the HYSYS process simulator was validated using experimental data obtained from a pilot scale cyclohexane / n-heptane distillation. The resulting model was linked to the pilot unit’s DeltaV (Emerson Process Management) process control software. This link allowed non-measured parameter estimation to occur in parallel with the operation and control of the pilot plant ...
متن کاملSuitability of Using Brass Ferrules as Packing in a Glass Distillation Column and Presenting a New Relationship between HETP and Pressure Drop
Brass Ferrules have been used as packing in a laboratory- scale glass distillation column approaching pilot plant size because of their availability in all sizes and low cost. The available size range is such that these ferrules could also be used in industry and the results of this study could be scaled up. The performance of the new packing has been compared with the performance of glass ...
متن کاملIdentification and Control of Multivariable Systems – Role of Relay Feedback
Batch and continuous systems are of multivariable in nature. A multivariable system is one in which one input not only affects its own outputs but also one or more other outputs in the plant. Multivariable processes are difficult to control due to the presence of the interactions. Increase in complexity and interactions between inputs and outputs yield degraded process behavior. Such processes ...
متن کاملMETHOD OF DESIGN FOR PACKED COLUMN TYPE HIDiC
INTRODUCTION In Japan, Pilot Plant of the HIDiC was built in 2005. It was commercial base scale and already achieved the consecutive distillation for 1000 hours. The energy consumption of the pilot HIDiC was only about 70% of that of a conventional distillation column. The HIDiC can lower reboiler and condenser load by heat exchange between rectifying section and stripping section. Therefore, i...
