how can I design a MPPT based solar charge controller using P&O algorithm by Matlab Simpower?

I've a model of a solar panel. Now I've to design a buck converter which is driven by PWM signals generated following the P&O algorithm for maximum power point tracking of solar panel. Please give some suggestions providing model of it at matlab simulink/simpower systems.

Hello Joyeeta,

Can you help me to check this code?

function dc = PyO( V, I, Adc, dcinit)
%#codegen
%Algoritmo P&O mi referencia es la tension de salida
% % Adc=3e-4; %Duty Cycle Variation

persistent dcold Vold Pold Iold
dataType = 'double';

if isempty(Vold)
    Vold=0;
    Iold=0;
    Pold=0;
    dcold=dcinit;
end
% dc= dcinit; 
%calculation 
P= V*I;

dcmax=0.7636; 
dcmin=0.15; 
% 
if P-Pold == 0
    dc=dcold;
    return
else
    if P-Pold>0
        if V-Vold>0
            dc = dcold + Adc; %incrementa V
        else
            dc = dcold - Adc; %reduce V
        end
    end
        if V-Vold>0
            dc = dcold - Adc; %reduce V
        else
            dc = dcold + Adc; %incrementa V
        end

      end
      if dc>=dcmax || dc<=dcmin
          dc=dcold;
      end
  dcold=dc;
  Vold=V;
  Iold=I;
  Pold=P;
