Quadruple tank process (QTP) can be configured both in minimum phase and non-minimum phase (NMP). However, in NMP, the control of QTP poses a challenge. This paper addresses that and presents a novel robust wavelet based non-minimum phase control (NMPC) strategy for the challenging QTP using genetic algorithm to find the optimised value of the manipulated variables in NMPC at every sampling time. The QTP is modelled based on wavelet neural network. The simulation results indicate that significant improvements have been achieved both in modelling and control strategies for a QTP system compare to conventional approaches such as the Levenberg-Marquardt.","PeriodicalId":360947,"journal":{"name":"International Journal of Process Systems Engineering","volume":"32 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115671874","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Discrete event simulation approach is used to give the effective solution to the problem. The aim of this paper is to redesign the assembly line and use of simulation environment in the production line, modular fixture design, optimisation of work assignment and further computer simulation for the determination of the optimal solution like production rate of the existing and then redesigned system by reducing the takt time of the line. A welding machines manufacturing company has a mixed model assembly line. Different models of the machine are assembled on the assembly line. In this paper, the Maynard operation sequence technique (MOST) work study is carried out to analyse and minimise the NVA activities. Further, WITNESS and ARENA simulation carried out to study the bottleneck operations and optimisation of work assignment to increase the production rate with less NVA activities. The results of the combination of the line balancing by changing the work assignment, redesigning the line and further process simulation raises the production rate of the process up to 20%.","PeriodicalId":360947,"journal":{"name":"International Journal of Process Systems Engineering","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127872507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three helical coils of coil diameter 110, 135 and 160 mm were tested. The effect of mass flux, coil curvature ratio and temperature difference between steam and tube inner wall on the condensation heat transfer coefficient were analysed. The condensation heat transfer coefficient increases with the increase in the value of mass flux. Temperature difference has substantial effect on the heat transfer coefficient. For the first time, the effect of coil curvature ratio on condensation heat transfer is studied and discussed in the paper. It is found that helical coil having greater coil curvature ratio has high values of condensation heat transfer coefficient in comparison to a low curvature ratio. Experimental results are compared with the work of earlier investigators. A new empirical correlation is developed to predict the condensation heat transfer coefficient.","PeriodicalId":360947,"journal":{"name":"International Journal of Process Systems Engineering","volume":"602 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121979710","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The spotlight has been turned on 'friction stir welding' as a joining technology, capable of providing welds that do not have defects normally associated with fusion welding processes. From the available literature, it has been observed that the effect of welding parameters on desired characteristics was determined by taking into consideration one parameter at a time or by using conventional methods. So without ignoring the limitations of earlier researches, the main focus in this study has been kept on welding of dissimilar aluminium alloys (AA6061 and AA5086) by using design of experiments which is quite rarely used multi-factor at a time technique. Tensile strength and hardness were identified as key mechanical properties and were optimised upto 0.156 KN/mm2 and 73.19 HVN respectively.

The DC microgrid is proposed for more efficient resilient electricity distribution in a commercial building. The operation strategy of energy storage systems (ESS) is proposed to solve the power changes from PV array and building loads fluctuations locally, instead of reflecting those disturbances into the utility grid. Furthermore, the ESS energy management scheme will help to achieve the peak reduction of the building daily electrical load demand. The DC microgrid studied in this paper is interfaced with the battery bank by using a bidirectional DC-DC converter, whilst the building electrical AC load is interfaced to grid using DC-AC inverter. The control of the studied microgrid is designed as a method to improve microgrid resilience and incorporate renewable power generation and storage into the grid.","PeriodicalId":360947,"journal":{"name":"International Journal of Process Systems Engineering","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129575157","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Now realising that this date is not that far away, it seemed appropriate that an interim evaluation of the progress that has been made should be done based on the available information. The review provides a clear picture of the advancement of inverter-based PV generation in the state of New York, how the state might use inverter-based solar to power residences, and the interconnection of microgrids. In this paper we present a summary of the findings that include lists of possible challenges in areas of the program. Our review indicates that a number of distributed generation resources is growing. But a lot more work needs to be done to include new technologies to reach the goal of non-carbon-based electric power system that would be able to meet the future electrical energy needs of the New York State safely and efficiently.","PeriodicalId":360947,"journal":{"name":"International Journal of Process Systems Engineering","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126822152","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, implementing energy management system(s) in such centres would be beneficiary to both economy and livelihood of environment. Additionally, harbouring renewable energy sources play a key and strategic role in policies circumventing both energy production/consumption and environment. Accordingly, design of a unique and comprehensive management system, with the focus on research institutes and organisations, for both energy efficiency improvement and renewable energy production seems to be inevitable. Here and for the first time, designing of an energy management system for such Iranian organisations has been proposed.

The hybrid grid consists of both AC and DC networks connected by a bidirectional AC/DC converter. Wind generator, AC loads and utility are connected to the AC bus whereas PV, energy storage system (ESS) and DC loads are tied to the DC bus. The coordination control algorithms of supervisor controller are proposed for smooth power management between AC and DC links and for stable system operation under various generation and load conditions. In this paper, a flexible supervisor controller is developed for a grid connected AC/DC microgrid, where the power flow in the microgrid is supervised based on demanded power with maximum utilisation of renewable resources and ESS. So, the objective of this paper is to use supervisory controller to control the transferred power from AC bus to DC bus and vice versa and control the charging/discharging power of the ESS to reduce the purchased power from the grid or to increase the sold power to the grid with respect to the load demand. The microgrid has been modelled and simulated using MATLAB Simulink. The simulation results show that the system can maintain stable under load variations.","PeriodicalId":360947,"journal":{"name":"International Journal of Process Systems Engineering","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122572557","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results show that the redox treatment of the YSZ−NiO ceramic specimens influences on their properties controversially. At the treatment temperature 600° a structure providing improved physical and mechanical properties of the material is formed. However, at the treatment temperature 800° an anode structure with an array of microcracks is formed that significantly reduces the strength and electrical conductivity of the material.
