Guide to Key Concepts

  1. State-Space Representations:
    • A state-space representation is a mathematical model that describes a system using a set of differential equations.
    • The state-space representation is of the form: $\dotx = Ax + Bu$, $y = Cx + Du$
    • where $x$ is the state vector, $u$ is the input vector, $y$ is the output vector, and $A$, $B$, $C$, and $D$ are matrices.
  2. Controllability and Observability:
    • Controllability: A system is controllable if it is possible to steer the state from any initial state to any final state in a finite time.
    • Observability: A system is observable if it is possible to determine the state from the output measurements.
    • The controllability and observability matrices are defined as: $C = [B, AB, A^2B, ...]$ and $O = [C^T, A^TC^T, (A^T)^2C^T, ...]$
  3. Eigenvalues and Eigenvectors:
    • Eigenvalues: The eigenvalues of a matrix $A$ are the values $\lambda$ that satisfy the equation $|A - \lambda I| = 0$.
    • Eigenvectors: The eigenvectors of a matrix $A$ are the non-zero vectors $v$ that satisfy the equation $Av = \lambda v$.
    • The eigenvalues and eigenvectors are used to diagonalize the state-space representation.
  4. Stability:
    • A system is stable if the state remains bounded for all bounded inputs.
    • The stability of a system can be determined by examining the eigenvalues of the matrix $A$.
    • If all eigenvalues of $A$ have negative real parts, then the system is asymptotically stable.
