Also, the contour plot of the same is depicted in the Fig. 17.The developed ANFIS model structure with 2 input neurons & 1 output neuron along with 4 hidden layers (input membership function, rule base, membership function, and aggregated output) are shown in the Fig. 18. The training of the neural network by using the fuzzy rule base for the selection of the proper & optimal rule is taken care of by the designed ANFIS controller. Note that 7 by 7 rules are used in the hidden layers. The neuron 1 is connected to 7 fuzzy rules & the neuron 2 is also connected to the 7 fuzzy rules. The hidden layers contains 49-49 neurons to deal the problem (for selection of the proper rule base, because the rule base are written randomly in fuzzy, the neural network selects the right optimal rule base to fire). The 2 input neurons, viz., the error, change in error is given as input to the 1st hidden layer of the ANN as shown in the Fig. 18. This 1st hidden layer deals with various input membership functions. In the 2nd & 3rd hidden layer, the set of 49 fuzzy rules are properly identified by training & the set of optimal rules are selected. These set of optimum rules are available at the 4th hidden layer. Out of the 49 rules, the optimal rules are fired here & the de-fuzzified output is obtained as the output neuron. The de-fuzzified output is further used to generate the firing pulse to be applied to the inverter bridge,which is further used to control the speed of the IM drive.
