how to model linear motion systems in matlab simulink

How do I model a simple linear system like the picture above in matlab simulink.

What should I do about this issue?

Can you give me a clue?

You can create a Simulink model for a linear motion system like the one shown in your image, which appears to be a ball screw actuator with a stepper/servo motor.

• A linear motion system in Simulink can be modeled by representing three main components: a motor (using transfer function), a ball screw mechanism (using gain blocks for rotary-to-linear conversion), and a load mass with friction.
• The system operates in a closed loop where the input position command passes through a PID controller to drive the motor, which then moves the load through the ball screw mechanism.
• The position feedback is compared with the input command to generate an error signal, allowing for precise position control.

Hoping this will give you some get starting ideas.
