- Why Interconnect Models?
Interconnecting models of system components allows you to construct models of control systems.
- Connecting Models
This example shows how to model interconnections of LTI systems, from simple series and parallel connections to complex block diagrams.
- Numeric Model of SISO Feedback Loop
Interconnect numeric LTI models to build a single model of a closed-loop system.
- Control System Model with Both Numeric and Tunable Components
Interconnect fixed components and tunable components to build a tunable control system model.
- Multi-Loop Control System
Build arbitrary block diagrams with any number of control loops by interconnecting models using the connect command.
- MIMO Control System
Build a MIMO control system with both fixed and tunable components.
- MIMO Feedback Loop
Obtain the closed-loop response of a MIMO feedback loop three different ways.
- Using FEEDBACK to Close Feedback Loops
This example shows why you should always use FEEDBACK to close feedback loops.
- Mark Analysis Points in Closed-Loop Models
Insert analysis points at locations of interest when you build control system models. Use analysis points for extracting system responses from the model.
- Control System with Multichannel Analysis Points
Build a control-system model with analysis points for extracting responses at different points in the system.
- Catalog of Model Interconnections
Block diagram connections correspond to model interconnection commands or arithmetic expressions.
- How the Software Determines Properties of Connected Models
When you interconnect models, the resulting model’s properties depend on the properties of the models you are connecting.
- Rules That Determine Model Type
Precedence rules determine the resulting model type when you interconnect models of different types.
- Recommended Model Type for Building Block Diagrams
Choice of model type can affect numerical accuracy when you interconnect models.
- Preventing State Duplication in System Interconnections
This example shows guidelines for building minimum-order models of LTI system interconnections.
