dynamically changing inductance value

I have at hand a Simulink buck-boost converter and a lookup table which outputs the value of L for current i.

I need Simulink to consistently update the value of L as the converter runs. Any idea how I can achieve this?

What I've tried: - I made my own inductor subsystem, takes in a voltage V and a value L as input, outputs the integral of V/L with respect to time (ie current). I plug the output into a controlled current source, it runs, but then gives me an error after a while saying my current source is open-circuited. - I have tried to define the inductor value as some constant L, but I'm not sure how to associate L with the output of the lookup table I have.

Any help would be vastly appreciated..

Simply put, how do I equate my inductance value to the output signal of the lookup table? :S

If using Simscape it is possible to use a Variable Inductor block:

If using a custom Simulink model you can feed back the current to as input to the lookup table.
