Please, I have completed my modeling and simulation is working fine for a sliding mode control system. However, I want to test the robustness of the controller with an input disturbance such as pulse and sinusoidal signal. Nevertheless, I am not sure if what i have done is correct. I conected the pulse signal with the input 'u' into the system via addition block of simulink. Please I have attached the coonection.
I would be gald for a better method of showing this because the plot is not giving desired result. I am using second order sliding mode - Twisting and Super-Twisting as my controllers. I am trying to investigate the differences between the two based on performances and others.

Yeah the two controllers are tracking perfectly. I have extended the time and they are still working perfectly. However, I have added pulse disturbance but i am doubting if i have done it correctly. The pulse disturbance time is also running the same entire duration of the system. I feel disturbance should just be for a fraction of the entire simulation time . For instance if simulation time is 10,000s, I want the disturbance to run for like 200s. How do i achieve this with pulse generator block or any other block in simulink.
