"WitrynaThe adaptive impedance controller consists of an impedance control part and an adaptive adjustment part. The input of the impedance control part is the difference between the desired contact force Fd and the actual contact force Fe and the output is a displacement offset Xf. And Δ X is defined as the output of the adaptive adjustment part. " - Impedance control in robotics
