UE Adaptive control systems

The Adaptive Control course covers fundamental concepts and practical techniques to achieve or maintain a desired level of performance in a control system, especially when the parameters of the plant model are unknown or change over time.

Outline :

1. Introduction to the adaptive control

Basic Adaptive Control Configurations, Application examples.

2. Parameter adaptation algorithms

Gradient algorithm, recursive least squares Algorithm, stability of parameter adaptation algorithms.

3. Identification in open loop – a brief review

Data acquisition, model complexity, parameter estimation, model validation.

4. Iterative identification in closed loop and controller redesign

Algorithms for identification in closed loop (CLOE, F-CLOE and AF-CLOE), Validation of models identified in closed loop, Iterative identification in closed loop and controller re-design.

5. Direct and Indirect Adaptive Control

Tracking and regulation with independent objectives (known parameters), adaptive tracking and regulation with independent objectives (direct adaptive control), pole placement (known parameters), adaptive pole placement (indirect adaptive control).
