The stability analysis of haptic systems without time-delay or with constant time-delay using the frequency-domain criteria such as Routh-Hurwitz or Nyquist has been found in many literatures. However, the stability analysis for the discrete-time haptic systems under time-varying delays remains a major challenge in the field of haptics. Based on the Lyapunov theory, this paper presents a sufficient stability condition in terms of LMI (Linear Matrix Inequality) for the discrete-time systems with… CONTINUE READING
