“…the most steps of the de rule ar, initialization, Evaluation, Repeat, Mutation, Recombination, Evaluation ,Selection, till (termination criteria are met).The block-diagram of DE is shown in Fig. For comparison DE algorithm with other optimization techniques (IWO),(SCA), and because the paper size limitation, all these techniques are not considered in detail, so that ,for (IWO) refer to Ref [25],and let the parameters of algorithm are:-Varmin=[0 0 0 0 0],Varmax=[ 10 10 1.5 10 1.5], maximum number of iterations=150, initial population size=2,maximum population size=10,minimum number of seeds=0,maximum number of seeds=5, variance reduction exponent=2,initial value of standard deviation=0.5 and final value of standard deviation=0.001.Table 4. indicates the FPID controller values depending on the performance index.…”
