Here is just the pic of a 1MW setup,, close enough to 1MW anyway.
All I need to do there is get all the parts to play nicely with each other.

IMHO I have supplied enough information for others to do what I have done.

It is not important as to HOW I am controlling this but more about the "what".
This system with and without the control is a resonant oscillator, kind of brings a slightly new meaning to the word, or use of the term, "resonance".

This is a downsized unit with only a single pivot.  I increased the rate of rotation as well as brought the arms up to a high rate as well.
I had to idealize the arms to rods so that the sim would not error.

I added 2 springs so that I could either add or subtract energy from the arms and in these 2 pics I am subtracting energy via the springs.
These 2 runs were from the same starting point the difference is in how I have my control system adjusted.

A small note,
This system is directional, that is if I rotate the wheel in one direction I as the operator can extract work, if I rotate it in the other direction I as the operator must supply work.

The system as shown is directional,, so here is a small scale low power slow version of both.

I have sim'ed this up for a real world build.
The pivot arms are now 30cm long, the pivot from axle is 30cm and the long arms are 75cm,, I have increased the working mass and made a few enhancements that I know how to make :)
I am rotating the wheel at 360 degrees per second, aka 60RPM and with approx. 265J per second gain I think that can overcome the losses of a motor and a generator.
Since I made changes to the setup I am only showing the power graph and the data file.

Made like this I think I can rotate a lot faster safely.

Due to my lack of skills in building, the increased complexity of the build is too much for me, with that I rolled back to a simplified version that I will build.
I have also included an auxiliary input by use of a constant force in, with this data set I have used 2 constant force springs to facilitate that input.
I need to add the auxiliary input to counter the real world losses the mechanical oscillator component has.

This is for a single system, where the build will have 2 systems and a full proper build would have a total of 6, 3 pairs of two properly phased to reduce the peak input torque of the drive motor and provide a more constant output.
