Two Link Pendulum State Space Model
State space equation derivation of an RR robot manipulator (two link pendulum) from the dynamics equations. Uses basic two-variable state vector, then expands to four-variable. Caveat - I am not a nonlinear controls expert, so this is just my best guess; video was made per request. For more information on nonlinear state space, see https://electronics.stackexchange.com...
