Which of the following best describes the primary characteristic of an adaptive control system?
Question 2
In Model-Reference Adaptive Control (MRAC), what is the primary function of the 'adaptation mechanism'?
Question 3
What is the main advantage of using a Self-Tuning Regulator (STR) over a fixed-gain controller when the plant parameters are unknown or time-varying?
Question 4
Which of the following is a key challenge in ensuring the stability of adaptive control systems?
Question 5
Consider a system with an unknown constant parameter $\theta$. An adaptation law is given by $\dot{\hat{\theta}} = \gamma \phi(t) e(t)$, where $\hat{\theta}$ is the estimated parameter, $\gamma > 0$ is the adaptation gain, $\phi(t)$ is a regressor, and $e(t)$ is the error. This type of adaptation law is commonly associated with which principle?
