ABSTRACT

The engineers do tremendous work to design a control system and expecting all conditions of

system operation, its ambient environment and its changes; and they calculate the parameters

of the controller according to that information. Unfortunately, when the control system is

realized and introduced to the real operation it is fail due to some unpredictable changes may

affect its performance or even take it to instability.

To over come this problem adaptive control system is used which has the property of

adjusting its parameters automatically to maintain the performance of the control system

within acceptable bounds. Several types of adaptive control systems are used today, one of

them is Model Reference Adaptive Control systems (MRAC). The model reference adaptive

control system is use a model which is fulfill the desired response and its output is compared

with the output of the system and the error between them is used to generate a control signal

which force the system to follow the model.

In this paper, a design of MRAC system for a speed control of a DC Motor is given. Also,

how the adaptive controller change its parameters to sustain the desired response of the

system.
