This paper presents novel method to control output error of the Photo Catalytic Sensor (PCS) using fuzzy interface. Whig and Ahmad in 2014, proposed the spice model of PCS which is a type of ion sensitive FET and very useful to estimate the parameter BOD (Biological Oxygen Demand) which is generally used to estimate quality of water. PCS can also be used to calculate the amount of concentration level of oxygen required to purify the polluted air and sanitization of surface. The purpose to control the output error due to variation in temperature is due to the fact that the fluctuation of O 2 influence the threshold voltage, which is internal parameter of FET can manifest itself as a voltage signal at output but as a function of trans conductance gain. Hence, a system controlled by fuzzy logic which control the output error is proposed. This novel method is very useful because of their simplicity, robustness and successful practical applications. The proposed system is fast in operation which is further helpful for PCS which operates under sub-threshold conditions and reduced computation time. The system is user friendly and the outcomes of simulation are fairly in agreement with the theoretical estimation.

Abstract-Increase in demand of electricity and clean drinking water has produced a chronic need of a promising and reliable technology for the supply of both commodities, which should be entirely based on renewable sources of energy. The authors, in their previous work, had proposed a design of a hybrid power plant which used graphene membrane for power generation using reverse osmosis process. The proposal included removal of arsenic, poorly biodegradable pollutants using TiO2 nanoparticles. Chlorine production using the process of electrolysis. The plant was also electronically implemented and included pump control, fouling detection modules and decision module for the volume of effluents to be discharged. The performance of a power system is essential to be analyzed for control, stabilization and efficient modelling. In the present research paper, simulation model of the hybrid plant is analyzed. The chemical behavior is analyzed with 'Watpro 3.0' industrial software and turbine governance system is studied via MATLAB. This plant is a potential replacement of chemical purification techniques with high overhead and excess cost. It is a better, efficient, safe and reliable system to produce clean and safe drinking water and electricity simultaneously.

Abstract:The Spice Model for photo catalytic sensor (PCS) proposed by Whig and Ahmad overcome several drawbacks like complex designing, non-linearity and long computation time generally found in Flow Injection Analysis (FIA) technique by Yoon-Chang Kim et al for the determination of Chemical Oxygen Demand (COD). FIA technique involves the complete analysis including sampling and washing. Flow Injection Analysis is analytical method for the measurement of chemical oxygen demand using photochemical column. This method uses a bulky setup and takes 10-15 minutes to get the output result which is a tedious and time consuming job. If conventional method is continuously used for a long time than it is stable only for 15 days. The purpose of this paper is to propose a new Quasi Floating Gate Photo Catalytic Sensor (QFGPCS) approach which has low power consumption and compared the results with the conventional models. The proposed model operates under sub threshold conditions which are appreciated in large integrated system design. The results of simulation were found to be fairly in agreement with the theoretical predictions. The results are exhibited near linear variations of parameters of interest with appreciably reduced response time.
