hello, Can someone please help write the following algorithm as a Matlab Function for Simulink? i am having trouble with the else statement and time increments. Thanks!

The prepared text/instructioins makes this appear as homework exercise -- it's general practice to coach/answer specific MATLAB Q? for homework, but not to just provide ready-to-run solutions...

So, show us your work so far and ask specifically where you've gotten stuck.

Thank you for your comment, i tried to model it in simulink but i couldnt model branched signals using the Merge block. i tried using signal conversion blocks as well but it did not work.

i tried using a Matlab function instead but i am stuck at using the else statement and defining simulation time increments, since it takes the Target point from the previous time step

I am not very proficient with matlab coding but this is the example i am working on. Any help, suggestions or guidance would be really helpful.

T_p = [30*pi/180; 30*pi/180]'; % + reference point

phi_p = T_p(1); %phi +

T_n = [-30*pi/180; 30*pi/180]'; %- reference point

phi_n = T_n(1); % phi -

tk = 0.1; %time step

t= 0:tk:10; %simulation time

phi = 50*cos(t);

theta = 40+30*sin(2*t);

%plot(phi,theta)

for k = 0:t

if phi > phi_p

Ta = Tn; %set target point

elseif phi < phi_n

Ta = Tp; %set target point

else

%i need to keep the values from the previous time step if else

%statement is executed

end

end

Hi @Muhammad Rameez Rashid.

You can go through the following documentation to understand writing if-else statements in MATLAB
