.Modelica_LinearSystems2.Controller .Modelica_LinearSystems2.ControllerThis package provides input/output blocks where every block is available in a continuous and a discrete (sampled) representation. A block is defined via its continuous parameterization. By specifying a discretization method and a sample time, the discrete representation is automatically derived from the continuous form. The defaults of the most important options for all blocks are set in the global SampleClock component (via inner/outer). As a result, it is, e.g., easy to switch quickly between a continuous and a discrete representation of all blocks of a controller.
Examples to demonstrate the technique are given in the package Examples. Especially, the continuous or discrete control of a simple flexible drive with a P-PI cascade controller is demonstrated in example SimpleControlledDrive.
