H Full Form
The HJI equation is named after Sir William Rowan Hamilton, Carl Gustav Jacob Jacobi, and Rufus Isaacs. Hamilton and Jacobi independently developed the equation in the early 19th century, while Isaacs extended the equation to apply to optimal control problems in the 20th century.
H Meaning
The HJI equation is a first-order partial differential equation that describes the value of the optimal control for a dynamical system. The value of the optimal control is the minimum cost of controlling the system from a given initial state to a given final state.
Essential Questions and Answers on Hamilton Jacobi Isaacs in "MISCELLANEOUS»UNFILED"
What is the Hamilton-Jacobi-Isaacs (HJI) equation?
The HJI equation is a partial differential equation that arises in optimal control theory. It is used to find the optimal control law for a given system.
