i forgot to write the solution... if anyone was interested or have similar problem y_{1} = \dot{x} y_{2} = x y_{3} = \dot{\theta} y_{4} = \theta \dot{y}_{1} = \ddot{x} \dot{y}_{2} = \dot{x} = y_{1} \dot{y}_{3} = \ddot{\theta} \dot{y}_{4} = \dot{\theta} = y_{3} \dot{y}_{1} =...

i am sorry, but i can't see how is your's supstitution different form mine when i wrote what i did to that point

yes, i know it has two columns. what is in a first? also solution to the eq? problem is i don't know how to solve it for x... can you say exactly how because i have no clue

thank you for your reply. i don't know if that is the method i am using but i know how to transform this second order to first order eq. and i got. \ddot{\theta} +\frac{F}{m*l}+ \frac{(m+M)*g}{l*m}\theta=0 \ddot{x}-\frac{F}{m}-\frac{g*M}{m}\theta=0 x_{1} = \dot{x} -> \dot{x}_{1}=...

hi, everybody i got for homework a pendulum on a cart. i solved the system and got two equations. (m+M)x'' + M L theta'' = F x'' + L theta'' + g* theta = 0 F = 1000 N, m = 500 kg, M = 1250 kg, l = 10m i know how to put them in state space and solve them with SS block in...
