How to check the stability analysis of completx opamp circuit in Ltspice

[newbie_hs]

I am attaching the simulation file of one of my circuit.It consists of many opamps and BJT's. I know how to check the stability of this circuit(I know it for single opamp circuits).

My input is V3(I_PT100_SET) and output is I_PT100_ACT .
I can see some ringing initially at output .

Can you please help me to check the stability and to compensate it.

Why not post a schematic for those who don't have LTspice at hand?

Your archive is bad, RAR wont open it. Do it again, also do it as zip format, and post them.

Your rar file opened fine in 7zip.
I don't see any design specs. You must have them.
I added test nodes on each output and squeezed the schematic and changed input to a square wave.

The integrator is drifting from DC offset.
