Fuzzy modelling of combustion efficiency and control of

At this point, obtaining an appropriate database is expected, which would be followed by designing the fuzzy rules for system modelling and data classification according to the efficiency of the boiler. At this stage, the data are segmented into predefined classes based on the classification criterion, i.e. the boiler efficiency.

Modelling, Simulation and Sensitivity Analysis of a Fatty

In order to investigate the sensitivity of the system, reflux ratio and reboiler duty were varied from 2.0-5.5 and 1350-1800 W, respectively. The results obtained from the steady-state simulation of the process revealed that the developed Aspen Plus model of the system was table because it was able to converge when simulated.

3. TS fuzzy modeling for the boiler–turbine system based on gap values We consider the following discrete affine TS fuzzy model to approximate the boiler–turbine system. Due to the load dependent characteristic of the power plant, power output x 2 is chosen as the unique antecedent variable. R i: if x 2(k)is Z i, then xðkþ1Þ¼A

Takagi-Sugeno (TS) Fuzzy System is one of the most popular method used for fuzzy modelling of multi input multi output (MIMO) dynamical system. In this paper, we propose an automatic tuning methods of fuzzy sets for TS fuzzy models using genetic algorithms. The effectiveness of the approach is illustrated by applying the method to a reboiler of batch distillation column. The …

Fig. 4. Block diagram of reboiler fuzzy model. Since we are only considering MISO fuzzy model, we have divided the system into two MISO system i.e. the jacket tank model and the vessel model. There are 4 and 3 inputs to the jacket tank and vessel models respectively. The range of values of the inputs and outputs of the fuzzy models are determined.
