PIDSimLab vs ControlsLab

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.

ControlsLab is a professional-grade system dynamics and controls simulator designed for engineering students, educators, and practicing engineers. Simulate a mass-spring-damper system in real time. Adjust parameters with intuitive sliders and instantly see how the system responds - no coding required, no MATLAB license needed.
