1 Answer. Sorted by: 1. I am guessing that you are looking for the transfer function from u u to y y, this would be consistent with current nomenclature. Taking Laplace transforms gives. (s2 + 2s)y1^ + sy2^ +u1^ = 0 (s − 1)y2^ +u2^ − su1^ = 0 ( s 2 + 2 s) y 1 ^ + s y 2 ^ + u 1 ^ = 0 ( s − 1) y 2 ^ + u 2 ^ − s u 1 ^ = 0. Solving algebraically gives.

The inverse Laplace transform converts the transfer function in the "s" domain to the time domain.I want to know if there is a way to transform the s-domain equation to a differential equation with derivatives. The following figure is just an example:The steady-state response is the output of the system in the limit of infinite time, and the transient response is the difference between the response and the steady state response (it corresponds to the homogeneous solution of the above differential equation). The transfer function for an LTI system may be written as the product:\$\begingroup\$ A differential equation is not a transfer function. Rather, a differential equation HAS a transfer function. Also, where you put equal signs, that's not an equality without equating coeffictients -- you show a specific transfer function next to a general form, which is convenient for looking things up on tables. \$\endgroup\$Transfer Function •Comparing electric circuits and mechanical systems. •The force-velocity column & the voltage-current column •The force-displacement column & the voltage-charge column •The spring & the capacitor •The viscous damper & the resistor •The mass & the inductor •Mechanical differential equations are analogous to mesh ...

The result will be the three-tuple [zz, pp, kk] , which consists of the values of the zeros, poles, and gain of G (s), respectively.We apply the Laplace transform to transform the equation into an algebraic (non differential) equation in the frequency domain. We solve the equation for X(s) . Then taking the inverse transform, if possible, we find x(t).
