Modelica.Clocked.Examples.CascadeControlledDrive

Examples based on a simple drive with cascade controller and different ways to define the sampling and super-sampling

Information

This package shows the same example in different variants.

Model CascadeControlledDrive.Continuous is the continuous-time model from which the sampled-data versions are derived. The "CascadeControlledDrive" example adds another position control cascade to the SimpleControlledDrive example. This model demonstrates a control system with two cascaded control loops. The goal is to control the angle of the load inertia.

The other example models under this package show different variants how the continuous-time model from above can be transformed to a periodic sampled-data system with two sample periods, where the two discrete-time controllers are precisely time-synchronized to each other.

Package Content

Name	Description
Continuous	Drive with continuous-time cascade controller
SubClocked	Drive with clocked cascade controller where clocks are defined with sub-sampling and partitions with super-sampling
SuperSampled	Drive with clocked cascade controller where fastest partition is defined with a clock and slower partition is defined with super-sampling
AbsoluteClocks	Drive with clocked cascade controller where all partitions are defined with exact (integer) clock that need to be compatible to each other

Modelica.Clocked.Examples.CascadeControlledDrive.Continuous

Drive with continuous-time cascade controller

Information

Original cascade controlled drive with a continuous-time controller.

Extends from Modelica.Icons.Example (Icon for runnable examples).

Modelica.Clocked.Examples.CascadeControlledDrive.SubClocked

Drive with clocked cascade controller where clocks are defined with sub-sampling and partitions with super-sampling

Information

Cascade control drive with discrete-time controller where one periodic clock is defined, the second periodic clock is derived by sub-sampling of the first clock, and both clocks are associated to the corresponding controller partitions. The super-sampling factor of block "super" is derived by clock inference.

Modelica.Clocked.Examples.CascadeControlledDrive.SuperSampled

Drive with clocked cascade controller where fastest partition is defined with a clock and slower partition is defined with super-sampling

Information

Cascade control drive with discrete-time controller where one periodic clock is defined for the fastest control loop, and the periodic clock of the slower control loop is implicitly defined by the super-sampling factor defined at the "super" block.

Extends from Modelica.Icons.Example (Icon for runnable examples).

Modelica.Clocked.Examples.CascadeControlledDrive.AbsoluteClocks

Drive with clocked cascade controller where all partitions are defined with exact (integer) clock that need to be compatible to each other

Information

Cascade control drive with discrete-time controller where two periodic clock with absolute periods are defined and are associated to the corresponding controller partitions. The super-sampling factor of block "super" is derived by clock inference.
