The Natura of Nonlinearity
Nonlinearity refs to a contenship in which thee output is not directly proporal al to te the input. In control systems, nonlinearity can arise from various sources, including:
- Fyzikal consiints of the system, such as saturation and dead zones.
- Dynamic changes in system parameters due to environmental conditions.
- Komplex interactions between een system condients.
