SISO Calculator vs PIDSimLab

SISO Calculator was built to help practicing engineers and students get an intuitive sense of System Dynamics and Controls. The interface is focused so you can quickly interact with controllers and plants to see immediately how time and frequency interact and how controllers behave.

PIDSimLab — PID Simulator PIDSimLab is a lightweight PID simulator built to help you understand and practice PID tuning. Adjust Kp, Ki, and Kd and instantly see how the system responds on a live step-response chart. Save traces and compare runs to find stable, fast, and smooth settings. Key features PID tuning: Edit Kp / Ki / Kd and observe the response immediately Time duration control: Adjust the simulation duration to observe system behavior across different time scales Start / Stop control: Run and pause simulations with a tap Test profiles: Try preset scenarios to speed up experimentation Real-time charts: Visualize the response curve as it evolves Save traces: Store runs and compare results across different settings Simple UI: Designed for quick learning and practical use PIDSimLab is useful for students, hobbyists, and engineers who want a clean, focused environment for exploring PID behavior.
