Control of nonlinear systems with application to a robot arm and a single-link robotic manipulator with a flexible joint

%% Part 1

% 2 integrators because you have two equations

%td = pi/4; %t2d = 0; A = [0 1;-64*sqrt(2)/2 -5]; B = [0;1]; % u_nom = 64*sin(pi/4) u_nom = 45.2548; F = lqr(A,B,eye(2),eye(1));

I am having trouble with the Simulink part1. This is my first control systems design on simulink and I have no clue on how to do this. Help would be appreciated. Thank you all. Please refer to the attach file for details.
