Triac control system for soft start

Hello,

I built a circuit in LTSpice in order to come up with a control circuit for the triac, which is designed to limit the current flowing to the receiver (which is the power supply), and without which there is an overvoltage that stops the voltage flow.
The plan is to design a triac control system that limits the current to 10 A but I don't know how to approach that.
The initial approach of applying a behavioral source of tension led to the analysis shown in the PDF document, which shows that this approach really has no effect.
What ideas do you have for the analysis circuit for LTSpice? I thought that the triac would control the zener diode, but I have too little experience to figure out how to work efficiently.
I am asking for help in inventing a system with a triac for soft start, so that a current of 10 A is constantly flowing to the receiver.

In the picture you can see a red rectangle and this is where you need to come up with a control system for a variable resistance load.

Best regards,
Anna
