If you change the control costs in the classical Linear Quadratic
tracking problem from a quadratic form, say u^2, to a term of the
form |u|, does anyone know what to do next?

Note that the Tracking error is still quadratic, so it is not obvious
that L_1 control helps.

I have the idea that this kind of problem may have been called "minimum
fuel" at some point, but I don't really know.

Thanks in Advance,
