Expansion Fraction Function Partial Systems Transfer function

AI Thread Summary

The discussion revolves around solving a control systems problem involving a system with a damping ratio of 0.5, a natural frequency of 100 rad/s, and a DC gain of 1, specifically finding the response to a unit step input. The main challenge highlighted is the difficulty in performing partial fraction expansion for the transfer function. Participants mention techniques such as cover-up rules and equating coefficients as potential methods for solving the problem. The conversation emphasizes the need for clarity in applying these mathematical techniques to achieve the correct response. Overall, the thread seeks guidance on effectively using partial fraction expansion in control system analysis.

Thread 'Find the distance given a function for v(t)'

My solution: v = 2*t + 5*t^2. dx/dt = 2*t + 5*t^2. Therefore dx = (2t + 5t^2)dt. After taking the anti derivative my equation is s = t^2/2 + 5/3(t^3).

Thread 'PLL - How to find all the gains of a PI corrector and fix Ki ? MATLAB'

Hello everyone, it's not really for my homework (because I'm not at school anymore) but I'm new and I don't know how to start a new forum. I've never done automatic before and I need help. I have a 2nd ordre PLL on MATLAB, with an NCO and a PI corrector; the PLL works via the Mid/End algorithm (that's part is ok). I need to find the link between the theoretical formulas and their values in the code to find the value of the gain Ki, and possibly that of Kp if it's not correct. Unfortunately...

Thread 'Have I solved this structural engineering equation correctly?'

Hi all, I have a structural engineering book from 1979. I am trying to follow it as best as I can. I have come to a formula that calculates the rotations in radians at the rigid joint that requires an iterative procedure. This equation comes in the form of: $$ x_i = \frac {Q_ih_i + Q_{i+1}h_{i+1}}{4K} + \frac {C}{K}x_{i-1} + \frac {C}{K}x_{i+1} $$ Where: ## Q ## is the horizontal storey shear ## h ## is the storey height ## K = (6G_i + C_i + C_{i+1}) ## ## G = \frac {I_g}{h} ## ## C...
