I´m doing a model for vehicle dynamics with a state space model. The state space model block includes the vehicle dynamics in matrix forms. However in the state space- block I can define just the A,B,C and possible D matrices. In the state space representation there are also dxdt (state variable derivatives), x (state variables), y (output vector) and u (input vector).
Is the u (input vector) the signal which comes into the state-space block input port in a form of vector?
Is the y (output vector) the signal which comes out of the state-space block output port in a form of vector?
Where do I include the x and it´s derivative dxdt?
Can I have a different name for the x? For example I would use v instead of x?
Thank you for helping me!
If you have a MIMO system with 3 inputs and 2 outputs, use Mux block with 3 inputs and Demux block with 2 outputs.
For your last question, the State Space block represent your Differential equation
but what about the x and dxdt symbols in the state-space form? Are they automatically created by implementing the A,B,C and (D) in the state-space block?
Does Simulink realize the real state variables just from the A,B,C and D matrices?
