Model Characteristics
The Control System Toolbox contains commands to query model characteristics such as the I/O dimensions, poles, zeros, and DC gain. These commands apply to both continuous- and discrete-time models. Their LTI-based syntax is summarized in the table below.
| Command |
Description |
|---|---|
size(model_name) |
Number of inputs and outputs |
ndims(model_name) |
Number of dimensions |
isct(model_name) |
Returns 1 for continuous systems |
isdt(model_name) |
Returns 1 for discrete systems |
hasdelay(model_name) |
True if system has delays |
pole(model_name) |
System poles |
zero(model_name) |
System (transmission) zeros |
dcgain(model_name) |
DC gain |
norm(model_name) |
System norms (H2 and L ) |
covar(model_name,W) |
Covariance of response to white noise |
