An economical adaptive controller is presented for flexible joint robots with arbitrary joint stiffness. It does not necessarily require the time derivatives of the regressor matrix while still providing stable closed-loop tracking performance.

โฆ Synopsis
A new adaptive controller for flexible joint robots is presented here based on singular perturbation theory and using only position and velocity feedback by modelling the 'motor tracking error' Ke, as the fast variables instead of the joint elastic forces, where K represents the joint elasticity and e, is the motor tracking error. The resulting boundary layer and quasi-steady-state systems are made exponentially stable: therefore the statements of Tychonov's theorem are valid for an infinite time interval.
