Abstract
This paper is an attempt to design an adaptive controller using model reference
adaptive control algorithm involving Indirect Field Oriented Control of an A.C.
Induction Machine as a nonlinear plant, without the need for modeling (knowing
the plant equations) except the plant order. The objective is to study the controller
parameters effect to reflect the performance specification in the control tasks, such
as rise time, settling time and overshoot in order to design a controller with an
adjustment mechanism so us the closed loop system remains stable. The second
plant used is a D.C. Motor as a linear plant to verify the capability of the
suggested method for a linear plant. The model is chosen with respect to the order
of the plant. The suggested method is to find the initial values of the controller
parameters by using a designed table which gives a good response compared with
the conventional method (tuned PI controller); in addition the designed controller
has an enhancement on the response with the time regarded to the adaptation
mechanism.
