State-Space Control Design and Estimation

Linear-Quadratic-Gaussian control, pole placement, Kalman estimators

Use state-space control design methods, such as LQG/LQR and pole-placement algorithms. The toolbox also provides tools for designing observers, including linear and nonlinear Kalman filters.

Nonlinear State Estimation of a Degrading Battery System

Estimate the states of a nonlinear system using an Unscented Kalman Filter in Simulink™. The example also illustrates how to develop an event-based Kalman Filter to update system parameters for more accurate state estimation. This example also requires Simscape™ and Stateflow®.
