GOOD. YOU SPOKE FIRST. THAT IS LESSON ONE: ZSIMPWIN DOES NOT RESPOND TO COMMANDS. IT RESPONDS TO INTENT. zsimpwin tutorial

Importing Data: Use the Paste button to directly input your dataset or open a supported file type (e.g., .txt or .csv) via the File menu. Click Simulate → Step Response Observe the curve:

Step 2 – Simulate Open-Loop Step Response

Click Simulate → Step Response
Observe the curve: initial flat delay, then exponential rise.
Note: Final value = ( K_p \times ) step size.

Inspect the data for obvious outliers or "noise loops" at high frequencies, which should often be excluded from fitting.
