ABSTRACT
This paper considers adaptive H-infinity control for robotic systems using only joint position measurements. We give a new class of adaptive control for robotic systems which are not only asymptotically tracking but also sub-optimal to some meaningful cost functionals. It is also shown that the derived systems are sub-optimal H-infinity control systems. Besides, the control system can be designed without solving the Hamilton-Jacobi-Isaacs equation. Numerical simulations are shown to illustrate the effectiveness of our method.
