By describing a plant dynamics in discretization form, Taylor series approximation can be applied to derive approximately stable inversion of the plant dynamics, which is required to design a disturbance observer. Appropriate truncation length of the Taylor series is investigated as a trade-off between the accuracy of the approximation and intentionally inserted delay for keeping causality. Finally, the inherent limitation of input current of plant is considered to get an optimal order.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e要約(英語): \u003c\/strong\u003e　This paper focuses on designing the disturbance observer by Taylor series approximation for a non-minimum phase system.
