Simulink Model Assistance for LADRC Control

Title: Help with Simulink Model for Frequency Response Under Random Disturbance with PID, FOPID, and LADRC Controllers

Description:

I am looking for an experienced Simulink and control systems expert to assist me in refining and completing my Simulink model, which simulates the frequency response under random disturbance. The project involves comparing the performance of three controllers: PID, FOPID, and LADRC.

Current Status:

I have already created and modeled the project in Simulink, including the key components such as:
A governor with deadzone
Reheat turbine models
Hydraulic turbine models
Control loops for the three controllers (PID, FOPID, LADRC)
The simulation is intended to show how the system responds to a random disturbance in frequency, and it should return to stability after the disturbance is resolved.
Challenges I’m Facing:

Although the controllers have been implemented, the outcomes do not meet my expectations. Specifically:
The response curves (PID, FOPID, and LADRC) are not behaving as expected. I need the simulation to exhibit specific characteristics:
The PID controller should show more oscillations with slower damping.
The FOPID controller should demonstrate fewer oscillations and better damping compared to the PID.
The LADRC controller should have the fastest response with minimal oscillations, achieving stability more quickly than the other two.
I need all controllers to remain at zero output before the disturbance occurs, show the disturbance response, and then return to zero once the disturbance ends.
I’ve struggled with properly tuning the controllers and setting the disturbance parameters in a way that yields realistic and expected results.
The plot should resemble a frequency variation chart (frequency over time) with the control dynamics clearly illustrated.
What I Need:

Expert help to review, correct, and refine the model to meet the intended outcomes.
Assistance in tuning the controllers (PID, FOPID, LADRC) so that the responses reflect realistic system behavior and the expected dynamic performance.
Guidance on setting up the disturbance correctly in Simulink (e.g., when it starts, how it affects the system, and ensuring the system stabilizes after the disturbance).
Help with generating plots that clearly show the system response for the three controllers over time, for comparison purposes.
Deliverables:

A fully functional Simulink model that simulates the correct behavior for the PID, FOPID, and LADRC controllers.
Properly configured controller settings and disturbance model.
Guidance or additional explanations on how the model works and how it can be tuned further in the future if necessary.
A plot that clearly shows the frequency variation for the three control systems over time, including oscillations, damping, and stabilization points.
