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.

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.

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

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.

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.

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".

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.

I might be wrong but I think that it is important to observe and understand that the system prior to the inclusion of the "control" device is a conservative mechanical oscillator.
I think this understanding of the conditions prior to the use of the "control" device makes it easier to understand that it is still only a conservative mechanical oscillator with the "control" device active and a load being taken out of the system.
In this setup there is no new energy being created or destroyed and that all the energy is accounted for.

and the last run

FYI,
The wheel radius is 4.5m
2.0400000000e+000 long arm kg
8.4000000000e-001 short arm kg
6.3617251235e+001 wheel kg
1.6400000000e+000 cross arm kg
6.0000000000e+000 spring rest length m
5.0000000000e+004 spring constant N/m

Then I increase the frames per second to get a closer look

Now I have added a load

I dropped down to one system and added a control device, which is not shown.
