REGULATOR BY SLIDING MODES WITH EXPONENTIAL HOLDER FOR LINEAR SYSTEMS

In a general command tracking and disturbance rejection problem, it is known that a sampled-data controller using zero-order hold may only guarantee asymptotic tracking at the sampling instances, but in general cannot guarantee the absence of ripples between the sampling instants. In this paper, a sampled-data robust controller using slide modes techniques and exponential holder is presented. It is shown that this controller ensures asymptotic tracking when applied to the continuous-time system.
