Controllability - Continuous Linear Systems

Continuous Linear Systems

Consider the continuous linear time-variant system

There exists a control from state at time to state at time if and only if is in the column space of

where is the state-transition matrix.

In fact, if is a solution to then a control given by would make the desired transfer.

Note that the matrix defined as above has the following properties:

  • is symmetric
  • is positive semidefinite for
  • satisfies the linear matrix differential equation
  • satisfies the equation

Famous quotes containing the words continuous and/or systems:

    “For Lawrence, existence was one continuous convalescence; it was as though he were newly reborn from a mortal illness every day of his life. What these convalescent eyes saw, his most casual speech would reveal.”
    —Aldous Huxley (1894–1963)

    “I am beginning to suspect all elaborate and special systems of education. They seem to me to be built up on the supposition that every child is a kind of idiot who must be taught to think.”
    —Anne Sullivan (1866–1936)
