Finding transfer function
May 14, 2020 · 2. Yes, your reasoning is right and is applicable to all control systems with a valid state space representation. The formula to go from state-space to transfer function can be easily derived like so: x ˙ = A x + B u. y = C x + D u. Taking laplace transform on both equations one by one. s X = A X + B U. i.e. ( s I − A) X = B U. The third part of the question says that for the element values shown, find the poles and zeros. It is clear from the transfer function that there is a zero at s = 0 rad/sec and a pole at $$\frac{1}{R(C1+C2)} = \frac{1}{100k*2*(0.5*10^{-6})} = 10$$ rad/sec. Are these answers all correct, and are they complete? Have I missed something?

All you need to do now is find an expression for the magnitude of the transfer function in terms of w and k, then choose some (frequency, magnitude) point on the plot and solve for k.A Transfer Function is the ratio of the output of a system to the input of a system, in the Laplace domain considering its initial conditions and equilibrium point to be zero. This assumption is relaxed for systems observing transience. If we have an input function of X (s), and an output function Y (s), we define the transfer function H (s) to be:To find the output, we multiply the transfer function by the input, and solve. We can find the inverse Laplace Transform by performing a partial fraction expansion to get the …
I want to find the closed loop transfer function. If there was no feedback (open loop), then I think I could find the output as Y(s) = Vin*G. This would mean that the transfer function is Y(s)/Vin = G.
