Adaptive Control

Adaptive control is a field of control that concerns systems with time-varying parameters. Adaptive Control alongside Robust Control were introduced to deal with uncertainties in the system model.

Categories

Adaptive control systems can be mainly categorized into two main groups:

• Indirect methods which estimate the system parameters (using methods like RLS, projection algorithm and …) and then use that information to change the controller parameters. Famous indirect methods include STR, …
• Direct methods which estimate the controller parameters directly. Famous direct methods include direct STR, model reference adaptive controllers (MRAC), model free adaptive control (MFAC) and … a
