The following diagram illustrates the relationships between the types of model objects in Control System Toolbox™, Robust Control Toolbox™, and System Identification Toolbox™ software. Model types that begin with id require System Identification Toolbox software. Model types that begin with u require Robust Control Toolbox software. All other model types are available with Control System Toolbox software.
The diagram illustrates the following two overlapping broad classifications of model object types:
Dynamic System Models vs. Static Models — In general, Dynamic System Models represent systems that have internal dynamics, while Static Models represent static input/output relationships.
Numeric Models vs. Generalized Models — Numeric Models are the basic numeric representation of linear systems with fixed coefficients. Generalized Models represent systems with tunable or uncertain components.
