3 Second Order Differential EquationsWe now turn to Second Order Differential Equations . Suchequations involve the Second derivative,y (x). Let s assume that we canwrite the equation asy (x) =F(x,y(x),y (x)).We would like to solve this equation using Simulink. This is accomplishedusing two integrators in Order to outputy (x)andy(x).input outputy y (b)input outputyy (a) outputyy input y (c) : Basic schemes for usingIntegrator blocks for solving secondorder Differential shown in (b), sendingy (x)into theIntegratorblock, weget outy (x). This is similar to usingy (x)to gety(x)in (a). Asshown in (c), combining twoIntegratorblocks, we can inputy (x) =F(x,y,y )and get outyandy . Feeding this output intoF(x,y,y ),we then obtain a model for solving the Second Order Differential general schematic for solving an initial value problem of the formy =F(x,y,y ),y(0) =y0,y (0) =v0, is shown in outputyy y F(x,y,y )y (0)y(0) : This is a general schematicfor solving an initial value problem ofthe formy =F(x,y,y ),y(0) =y0,y (0) = this chapter we will demonstrate the modeling of Second Order con-stant coefficient Differential Equations and show some si
