This video shows the steps to design a differential equation 2nd order in Simulink using basic blocks in Matlab 2017b.
Differential Equation in Simulink
2 x” + 2 x’ + 3 𝑦’ + 𝑥 + 2𝑦 = 0,
𝑦” + 𝑥’ + 2 𝑦’ + 2𝑦 = sin(𝜋𝑡)
𝑦'( 0 )= −1
y( 0 )= 1
x” = -1/2 ( 2 x’ + 3 𝑦’ + 𝑥 + 2𝑦)
𝑦” = sin(𝜋𝑡) – 𝑥’ – 2 𝑦’ – 2𝑦

The maximum height ‘h’ achieved by an object thrown with a speed ‘v’ at an angle ‘theta’ is given by h=v(sqr)*sin(theta)(sqr)/2g . Create a table showing the maximum height for the following values of v and theta. v=10 20, in steps of 2 and in steps of 10. Use suitable interpolation function to find ‘h’ corresponds to v=13 & 15 and theta = 55 to 65You can watch my this video: https://youtu.be/LPc-OsU8gb4I have shown the steps to interpolate using the interp1 function of matlab.
How do you take care of the initial conditions ?
Initial conditions can be given in Integration Block. Open the integrator block parameter window by double clicking the block and there you will get the option to enter initial condition.I think I have shown this step in my “spring mass damping” video. You can refer to that video by using below link :
