Construct reference model for adaptive controller.
显示 更早的评论
iam using model reference adaptive controller but i can not construct the reference model , i found there are method for constructing reference model :Zero-pole and frequency but i dont know how to use them or even apply them to my simulink model.

Hi @Nour Akmal
Perhaps you can describe how the system state should behave according to the desired reference in your mind.
You can even sketch the desired state trajectory over the time interval from the initial value until the desired final value.
Else, you can try adjusting the parameter given in this code, until the desired settling time and overshoot are achieved.
param = sqrt(2); % recommend to adjust between 0 to sqrt(2)
Gr = tf([param 1], [1 2 1])
Gr = zpk(Gr) % in Zero-pole-gain model
Rss = ss(Gr) % in State-space model
step(Gr, 10)
S = stepinfo(Gr)

You're welcome, @Nour Akmal. You can use one of the three types {transfer function (tf), zero-pole-gain (zpk), state-space (ss)} to describe the linear reference model. As long as the desired state trajectory looks logical for your Voltage Source Converter, you can use it.
