Question
Derive the state-space model (state equation and output equation) in vector form for the
following system. The system outputs are the displacements of each spring. Assume that the
connection between the spring and rope is massless and that the rope is inextensible. Assume
that gravity is an input as well as the applied forces Fi(t) and F2(t). Neglect friction forces
on mass m₂.
If q₁ is the state variable for the bottom spring connected to m₁, q2 is the state variable for the
mass m₁, q3 is the the top spring connected to the pulley, and q4 is the state variable connected
to the mass m2, then you should expect to get the following state-space representation:
