TI  - A nonlinear disturbance observer scheme for discrete time control systems
AB  - This paper presents a modification to the original disturbance observer based control (DOBC) scheme by
redefining the lowpass filter using a nonlinear element. The proposed technique improves the disturbance prediction
performance for both small and large magnitude disturbance signals. The contribution of the current work is to unfold
the stability and performance conditions under the proposed modification. A comparative set of simulation studies are
discussed and it is seen that the proposed modification results in smaller disturbance prediction error energy and smaller
tracking error energy when the plant model is discrete time and uncertain.
