This idea is similar to locally optimal control from the state-dependent Riccati equation control [18, 19].

This approach was further investigated by Coultier et al., who extended the LQR approach to propose a so-called state-dependent Riccati equation (SDRE) method for the nonlinear quadratic regulation problems .
where P(x) is the symmetric and positive-definite solution of the algebraic state-dependent Riccati equation as
In this paper the state-dependent Riccati equation technique was used to control AIDS.
Keywords: State-dependent Riccati equation (SDRE), human immunodeficiency virus (HIV), Affine, Linear Quadratic Regulator (LQR), State Dependent Coefficient (SDC)
The problem of designing satellite nonlinear controller for rigid satellite has been done by Souza and Gonzales  using the state-dependent Riccati equation
(SDRE) method which is able to deal with high nonlinear plants.
Within the framework of the state-dependent Riccati equation
, Friedland  proposed to apply to the system a physical constraint modeled by a nonlinear spring which provides a state-dependent restoring force that is accounted for in the controller design.
