Where's the input for u at the Simulink Kalman Block?

Hi everybody!

I'm trying to use the Kalman Filter Block of Simulink and I can't figure out how to get my sensor signal u into that block.

Normally you use a state space model of this type
(I used continious time just to show what I mean):

x_dot = Ax + Bu
z = Cx

But the Kalman Block only offers a z-Input!?!?!

I tried to remodel my equations to define my input vector u as a state x. But that changes my dynamic system...

Is there any way to get my signal into that block? Or do I have to design my Kalman filter from scratch?

Thanks a lot!
Volker
