The error refers to the state matrix that is returned from the lin operation and simply indicates that the state matrix computed is singular to working precision.
Help linearizing simulink model. "The value of the "A" property must be a numeric array without any Inf's or NaN's"

I have constructed a linear simulink model from a nonlinear model. The linear representation is included as an ss block. A controller and actuator dynamics have been introduced to examine the effects of slew rate limits. A pic of the model is attached.
When linearizing the model to obtain the closed-loop (broken-loop/dist/etc) response using the linear analysis design tool I am recieving the error
"The value of the "A" property must be a numeric array without any Inf's or NaN's"
While the condition number of the state matrix is relatively large (1.0377e+004) the state matrix is not singular. Naturally the elements of the state equation contain numeric values.
Searching the forums this does not appear to be a common error.
Any assitance in interpreting this error message would be most welcome.
Best,
Jamie
