Control, estimation, and optimal decisions

Analyze how inputs shape dynamical systems through controllability, observability, feedback, and optimal control.

  1. 01

    State-space models and input–output maps

    Separate internal state, forcing and measurement while deriving a causal response from the matrix exponential.

    27 min
  2. 02

    Controllability and reachability Gramians

    Connect algebraic rank with finite-time state transfer and quantify the input energy required in each direction.

    31 min
  3. 03

    Observability and minimal realizations

    Recover internal information from output histories and identify the modes a transfer experiment cannot reveal.

    29 min
  4. 04

    State feedback and pole placement

    Design a closed-loop characteristic polynomial while separating assignable modes, stabilization and implementation limits.

    29 min
  5. 05

    Lyapunov equations and stability margins

    Build an energy certificate for a Hurwitz matrix and quantify a sufficient perturbation bound in that chosen metric.

    31 min
  6. 06

    Linear-quadratic regulation and Riccati equations

    Derive a feedback law from a quadratic value function and select the stabilizing Riccati solution with explicit hypotheses.

    34 min
  7. 07

    Kalman filtering and estimation error

    Combine a dynamical prediction with a noisy observation while distinguishing covariance bookkeeping from actual model accuracy.

    32 min
  8. 08

    Pontryagin’s maximum principle

    Derive state–costate necessary conditions while keeping sign conventions, endpoint rules and normality explicit.

    34 min
  9. 09

    Hamilton–Jacobi–Bellman equations

    Turn remaining optimal cost into a feedback equation and verify a policy by integrating a pointwise inequality.

    34 min
  10. 10

    Robust control and the small-gain theorem

    Bound uncertain feedback amplification using causal gains while retaining well-posedness and internal-stability qualifications.
