.Modelica_LinearSystems2.WorkInProgress.StateSpace.Examples.designInverseDoublePendulumController

Information

This example demonstrates how to design pole placement controller to balance an inverted double pendulum. For controller design a linearized model of a (simple) physical system model is used. The controller is applied to the physical model in Moldelica_Controller library.

It is also shown how to linearize a modelica model. The linear model is used as a base for control design
