Abstract :
This paper proposes a design of frequency shaped sliding mode controller using fast output sampling technique. A compensator is introduced in the sliding surface to attenuate the frequency component of the sliding mode dynamics so that the unmodelled dynamics are minimally excited. The fast output sampling technique is used to estimate the states of the system where the output is measured at a faster rate than the input updates. The control law performance is validated by the simulation.
