linearization
Mathematical term for approximating a nonlinear function or system with a linear one, often using derivatives or Taylor expansion.
Linearization of nonlinear systems is a technique often used in control engineering.
We use Taylor expansion for the linearization of this function.
非線形 means 'nonlinear', the opposite of 線形. 線形化 is often applied to 非線形 systems.
Compound of 線形 (linear) + 化 (-ization). The term is a direct calque from English 'linearization'.
