 This is a Matlab code collection of control experiments.
 
 System to be controlled:
-- A crane that moves along an one-dimensional track.
+- A crane that moves along 1-dimensional track.
 - It behaves as a frictionless cart with mass M actuated by an external force F that constitutes the input of the system.
 - There are two loads suspended from cables attached to the crane.
 - The loads have mass m1 and m2, and the lengths of the cables are l1 and l2 respectively
