Many components and actuators have non-linear characteristics and the effectiveness of their action requires that they remain at the point of operation where they act approximately linearly, which can be a very limited interval. For example, the music that we all hear must be amplified by a circuit composed of electronic devices that only amplify the signal when they are acting at the point of operation in which the system is designed to act linearly; proof of this is that the output of the system as a whole is proportional to the input, that is, a linear system.

What is linearization? It is to express a non-linear function or differential equation with an approximate linear version, only valid in a very small range of values of the independent variable.

As: We find the following values and substitute them in the previous equation: Then we can represent our nonlinear system by means of the following negative line equation:. Suppose now that our system is represented by the following differential equation: The presence of the term cosx makes the previous one a non-linear equation.

Note that in the previous equation the excursion is zero when the function is evaluated exactly at the point xo. The same happens when the slope is evaluated in xo : So:. The Taylor series enables us to work with functions or differential equations that have two independent variables. In what do the green dots mean on match regard, the Taylor series applies the following formula:.
