1. What are the different types of adaptive schemes? Explain in detail. [12]
2. Consider a system described by a model.
dy/dt= - ay+bu,
Where u is the control variable and y is the measured output. Assume that we want to
obtain a closed loop system described by dym/dt= -amym+bmuc u(t) = θ1uc(t)-θ2 y(t).
Design a Model reference adaptive system (MRAS) using MIT rule. [12]
