Abstract: In this paper, the Sliding Mode Control (SMC) is incorporated with Time-Delay Control (TDC) during sliding phase to reduce the switching gain. TDC identifies the unknown system dynamics and disturbance directly every delay-time. For a system with a lumped perturbation which is relatively slow varying with respect to the sampling interval, a much low switching gain can be used if a reasonably good estimate of the derivative of system state can be obtained using the past information, hence chattering can be reduced or eliminated while retaining the tracking accuracy. This paper considers unmatched uncertainties. It is an extension of [1].
