Linearizing a system
NettetThe slope m of the line can be defined as the tangent function of the angle (α) between the line and the horizontal axis: \[m = tan(\alpha) = \frac{dy}{dx} \tag{2}\] where dy and dx are small variations in the coordinates of the line.. Another way of defining a line, is by specifying the slope m and a point (x 0, y 0) through which the line passes.The … Nettet5. mar. 2024 · The behavior of a nonlinear system, described by \(y=f(x)\), in the vicinity of a given operating point, \(x=x_0\), can be approximated by plotting a tangent line to the …
