Making LLC controller in LTspice

[cupoftea]

Hi,
I am trying to make an LLC controller in LTspice.
So I have the error amplifier voltage V(EA), and I need to vary the period of the
FET driver oscillator in accordance with this.
Do you know why my attached version does not work?

I believe I am violating some LTspice syntax but extensive web searching still doesn't allow
me to find out that I am doing wrong

Perhaps i should be using Qspice instead?

Looks to me like you have cart before horse, .param
assignments based on simulation results?

T1 based on a V() argument and the rest are derivative
case-assignments.

I believe you need your logic done circuit-style (timing
ramp & compare)?

How you will set the pulse timing for the ZC / ZS
switching (getting the desired half-period sine
of this resonant style to "stick the landing"), I do
not see either. Set-and-forget, and tolerate any
deviation, or "servo it"?

Parameters aren't updated during simulation run and can't be made e.g. node voltage dependent. Also vpulse parameters can't be varied dynamically. Not specific to Ltspice.
