Lead-Compensator
About the Lead-Compensator PCB
Lead-Compensator is an open source PCB design by ardagurbuuz, published on GitHub. It is a 2-layer board measuring 88.5 × 57.5 mm, with 29 components from 15 distinct parts.
Other key parts include the TL074 and TL071. By type, the board carries 15 resistors, 4 capacitors, 2 ICs and 1 switch.
From the project
Analog lead compensator for a second-order plant to improve transient performance (reduced overshoot, faster settling).
This repository documents an end-to-end control + hardware workflow: designing a lead compensator, validating it at model-level (MATLAB/Simulink) and circuit-level (SPICE tools), and implementing it as an op-amp analog controller on a KiCad PCB.
A benchmark plant model is used as the baseline system:
1. Uncompensated loop: plant-only closed-loop response 2. Compensated loop: plant + lead compensator closed-loop response
