How do you Linearize a nonlinear state space model?
Linearization of State-Space Models
˙x=f(x,u)(nonlinear state-space model)x=(x1⋮xn),u=(u1⋮um),f=(f1⋮fn), we can apply Taylor expansion in multivariables. Assume x=0,u=0 is an equilibrium point: f(0,0)=0, i.e., when the system is at rest and no control is applied, the system does not move.
What does it mean to Linearise a system?
In the study of dynamical systems, linearization is a method for assessing the local stability of an equilibrium point of a system of nonlinear differential equations or discrete dynamical systems. This method is used in fields such as engineering, physics, economics, and ecology.
What is the state space of a system?
A state space is the set of all possible configurations of a system. It is a useful abstraction for reasoning about the behavior of a given system and is widely used in the fields of artificial intelligence and game theory.
Can state space model nonlinear systems?
The nature of state-space models make them very desirable for analyzing or de- signing a system [18]. First, state-space models can very easily and naturally handle nonlinearity in the model.
