Web-Based Control System Analysis and Design
Member function append() group two LTI models by appending their inputs and outputs. It returns a block-diagonal, unconnected LTI model.
The function appends the inputs and outputs of the LTI models Sys1 and Sys2, which are
represented in state space models as (A1,B1,C1,D1) and (A2,B2,C2,D2), to
form the resulting model Sys. The matrices of state space model (A,B,C,D) of Sys
with n submodels is shown as below.
If the systems are created in other models rather than state space, they will be changed to state space models
by Ch Control System Toolkit automatically.
