Control System Designer

Design control systems with dynamic plots, draggable blocks, and advanced features.

How to Use

- Enter base TF coefficients in the left panel.
- Drag blocks (Lead, Lag, PID, Notch) to the chain.
- Edit blocks in the chain editor or via popup.
- Adjust K range and frequency in plots.
- Use undo/redo, save/load, and export options.
