Multi-dimensional State-Space model in Simulink
6 views (last 30 days)
As a result from a certain model, I get a 3x3 SS. There are three inputs (Acceleration x, Acceleration y, Acceleration rz) and three outputs (Pressure x, Pressure y, Pressure rz).
However, I only know how to implement one of the 9 (3x3) SS representation (for example acceleration x to pressure x) in the `State-Space' block.I know how to mux and demux the acceleration and pressures.
So my question is: How do I get the 3x3 SS in one `State-Space' block?

If you have the state-space description of you 3 x 3 system, why don't you just enter it into the parameters of the state-space block? It accepts matrices for B, C and D, not just vectors. The only obstacles I can imagine is that you might not be able to enter 0 for D, but it would have to be zeros(3,3).
