Based on your comment on other question for expression of ea(t): https://www.mathworks.com/matlabcentral/answers/541922-please-tell-me-how-to-use-ode45-code#comment_883106 the following shows how to use ode45 to solve this ODE with input saturation
[t, y] = ode45(@odeFun, [0 1], [0; 0]);
plot(t, y(:,1), 'o-')
function dxdt = odeFun(t, x)
% transfer function is equivalent to following ODE
% x'' = 4/9(-16x'+ea(t))
ea = (1-x(1))*303;
if ea > 100
ea = 100;
elseif ea < -100
ea = -100;
end
dxdt = zeros(2, 1);
dxdt(1) = x(2);
dxdt(2) = 4/9*(-16*x(2)+ea);
end
