ABSTRACT In this paper, a composite antidisturbance control scheme based on robust disturbance interval observer (RDIO) is proposed for class of nonlinear systems with multiple disturbances. Considering the uncertainties in asymmetry bounds, different from existing scheme, here RDIO designed utilizing uncertainty information to obtain possible real disturbance, and effect suppressed by compressing performance. The comparison estimation accuracy traditional (DO) given theoretical analysis. Furthermore, algorithms solving parameters are provided generalized specific situations. Based integral sliding mode (ISMC), controller compensation attenuation ability realize high‐precision stabilization. Finally, effectiveness superiority verified numerical simulation application motor rotation tracking hardware‐in‐loop (HIL) experiment.
