Data on fuzzy logic based-modelling and optimization of recovered lipid from microalgae

This article presents the data of recovered lipid from microalgae using fuzzy logic based-modelling and particle swarm optimization (PSO) algorithm. The details of fuzzy model and optimization process were discussed in our work entitled “Application of Fuzzy Modelling and Particle Swarm Optimization to Enhance Lipid Extraction from Microalgae” (Nassef et al., 2019) [1]. The presented data are divided into two main parts. The first part represents the percentage of recovered lipid using fuzzy logic model and ANOVA. However, the second part shows the variation of the cost function (recovered lipid) for the 100 runs of PSO algorithm during optimization process. These data sets can be used as references to analyze the data obtained by any other optimization technique. The data sets are provided in the supplementary materials in Tables 1–2.

Data
This article presents the numerical data generated during the maximizing of recovered lipid from microalgae using fuzzy logic based-modelling and PSO algorithm. The simulation was carried out using Matlab/Simulink software package on a Core i7 computer with Win10 operating system. The data generation process comes with some stages. First, by using the experimental data from Refs. [1,6], a robust model that describes the lipid extraction is generated using fuzzy logic technique. Table 1 (supplementary materials) shows a comparison of fuzzy based model with ANOVA. Second, the optimal decision variables for extracting the lipids are determined using PSO algorithm. During optimization process, three different operating parameters; power (W), heating time (minutes), and extraction time (hours) have been used as a decision variables in order to maximize the percentage of the recovered-lipid which is used as a cost function. Due to the stochastic behavior of the swarm optimizers, the optimizer results cannot be trusted unless many trials have been done [7e9]. Therefore, the optimization process was executed for 100 times. The data of the 100 runs is presented in Table 2 (supplementary materials).

Experimental design, materials and methods
A sample of 500 ml of the wet algae was subjected to microwave pre-treatment using a round bottom open glass. The samples were pre-treated at a microwave power ranging between 180 W and 600 W for times ranging between 2 minutes and 8 minutes. Furthermore, different extraction times were tested between 3 and 4 hours.

Finally, PSO algorithm has been used to identify the optimal operating parameters to maximize the recovered lipid. Tables 1 and 2, in Appendix-A, show the outputs of the fuzzy model and the results of optimization process, respectively.
