.Modelica_LinearSystems2.Utilities.Plants.DoublePendulumInverse .Modelica_LinearSystems2.Utilities.Plants.DoublePendulumInverseMultibody model of a simple inverted double pendulum system. This physical model is used in various models and functions of the library, e.g. for linearization or as a base for linear controller design. The initial values are used as a working point for linearization.
