# Control State Equations

Use the State Equations tool to create and set control state equation data.

## Create Control State Equations

A control state equation is an entity that can be used to model any generic dynamic system in an abstract manner.

## Edit Control State Equations

A user subroutine is used to describe the behavior of the dynamic system. The dynamic system is characterized by a vector of inputs u, a vector of dynamic states x, and a vector of outputs y. The state vector x is defined through a set of differential equations. The output vector y is defined by a set of algebraic equations.

### Define the Properties of Control State Equations

From the Properties tab, you can provide inputs needed for the control state equation.

### Define the User-Functions of Control State Equations

The User-Function tab is used to provide user subroutine related information for the control state equation.
