WebInput-Output Linearization The Normal Form decomposes the system into an external part ˘and an internal part . The external part is linearized by the state feedback control u = (x) + (x)v The internal dynamics is described by (6). Setting ˘= 0 in that equation results in _ = f 0( ;0) (9) which is called the zero dynamics. WebMar 11, 2024 · Linearization is the process in which a nonlinear system is converted into a simpler linear system. This is performed due to the fact that linear systems are typically easier to work with than nonlinear systems. For this course, the linearization process can be performed using Mathematica.
