.Modelica_LinearSystems2.WorkInProgress.StateSpace.Examples.designCraneController

Information

This example demonstrates how to design a lq-controller or a pole placement controller respectively. Compared with example craneController, the plant is smaller to achieve suitable dynamics for animation. The feedback matrices and a simple pre filter for tracking are save to MATLAB files which can be used in ModelicaController library.

It is also shown how to linearize a model of a crane trolley system [1]. The linear model is used as a base for control design
