Disturbance (%)

Feedback measures the output, compares it to the target, and corrects the difference. High loop gain shrinks both tracking error and the effect of disturbances by a factor of 1+G — which is why feedback control is everywhere, from thermostats to cruise control. Educational tool.

Disturbance rejected98%

Governing equation

T = \frac{G}{1 + G H} = \frac{50}{1 + 50 \cdot 1} = 0.980

Reading this result: Moderate gain divides both tracking error and disturbance by 1+G = 51×, cutting the 30% open-loop error down to 0.6%.

About this simulation

The full Feedback Loop tool models a walking robot with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
