Review of Model Reference Adaptive Control

Adaptive control is a technique used for adjusting the parameters of a plant in real-time in order to maintain a desired level of performance when the parameters of the system are unknown and/or change with time. Model reference Adaptive Control (MRAC) offers an approach for the solution of problems related to Adaptive Control in real world. By creating a closed loop controller MRAC tries to compare the output of the plant with a standard reference response and various parameters of the plant change with this response. In this paper we had discussed about Adaptive Control, Model Reference Adaptive Control (MRAC), its historical perspective, its working, the rules that govern MRAC, its real-world applications and the present scenario.
