  • Abstract
    In a recent paper Tomei (1991) presented a globally asymptotically stable PD regulator for robots with flexible joints. A drawback of this scheme is that the noise in the velocity measurements degrades the performance. In this paper we show that the velocity measurement in Tomei´s scheme can be replaced by approximate differentiation preserving global asymptotic stability. Simulations that illustrate our result are presented
