The paper presents the identification issues of the self-tuning nonlinear controller ASPECT (Advanced control algorithmS for ProgrammablE logiC conTrollers). The controller is implemented on a simple PLC platform with an extra mathematical coprocessor, but is intended for the advanced control of complex processes. The model of the controlled plant is obtained by means of experimental modelling....
Rapeseed waste from biodiesel production was explored as a biosorbent for the removal of Cu(II) and Cd(II) ions from aqueous solutions under batch conditions. The optimum value of the initial pH for the sorption of both metal ions was found to be 4.5 to 5. The efficiency of Cu(II) and Cd(II) removal from aqueous solutions varied from 49% to 91% and from 61% to 97%, respectively, by increasing t...
A new approach is presented in this paper for the display and processing of electrodermal activity. It offers a fully automated interface for the pre-processing and scoring individual skin conductance responses (SCRs). The application supports parallel processing by means of multiple threads. Batch processing is also available. The XML format is used to describe the derived features. The system...
An integrated strategy for the tracking control of product qualities in batch processes is proposed by combing batch-to-batch iterative learning control (ILC) with on-line shrinking horizon model predictive control (SHMPC) within a batch. ILC is used in batch-to-batch control and the convergence of batch-wise tracking error under ILC is guaranteed. On-line SHMPC within a batch can reduce the ef...
conclusions with the proper operation of wastewater the treatment plant and increasing the retention time, the removal efficiency of the detergents increased. in addition, according to the environmental standards for bod5, cod and the detergents, the results of the present study indicated that the outputs of these parameters from the sbr system were appropriate for agricultural irrigation. resu...
This paper proposes a method by means of which it is possible to calculate the circulation and evaporation rates and thus optimise the design of pans. It is shown that when designing batch pans there is an optimum combination of tube length, diameter and circulation ratio to produce maximum circulation for a given graining volume and heating surface/volume ratio. Similarly when designing contin...
In this paper we present a new clustering algorithm which extends the traditional batch k-means enabling the introduction of domain knowledge in the form of Must, Cannot, May and May-Not rules between the data points. Besides, we have applied the presented method to the task of avoiding bias in clustering. Evaluation carried out in standard collections showed considerable improvements in effect...
The complexity of decision-making in process industries and the need of highly competitive organizations require new supporting tools to coordinate and optimize the information flow among decision levels. This work presents a framework for integrating the scheduling and control decision levels by means of an ontology, which allows and coordinates the information exchange among the different mod...
