Consider the following system of equations of a single link robotic manipulator with a flexible joint
I6, (t) + mgl sin 1 (t) + k(6, (t) – 02 (t)) = 0
JÖ, (t) – k(0, (t) – 02 (t)) = u(t)
where 01 (t), 02 (t) are the angular positions, I, J are moments of inertia, m, l, k are link mass, length and spring constant respectively. Introduce the change
of variables as r1(t) = 01 (t), x2(t) = 01(t), x3(t) = 02 (t), x4(t) = Ô2(t) Find the linearised state space model of the system with equilibrium conditions
[x; x; x; x]T. Take the values of k = 0.5 N/m; g= 9.8m/s²; m = 0.5 kg; l = 0.5 m; I =1 kg. m²; J = 0.5 kg. m² .
