Abstract:
|
This paper presents a Sliding Mode Control for a
wound rotor synchronous machine acting as an isolated generator
connected to an unbalanced load. In order to simplify the control
methodology, the standard dq-model of the machine is connected
to a balanced resistive load. A switching function is defined in
order to fulfill the control objective. From the desired surface, the
standard sliding methodology is applied to obtain a robust and
very simple controller. Then, the actual measured voltage of the
machines is acquired and treated trough a frequency locked loop
algorithm in order to extract the positive sequence and control
it to guarantee a good definition of the park transformation. A
phase locked loop algorithm is also used to avoid speed sensors.
Numerical simulations a validate the control law and show good
performance and a fast response to load and reference changes. |
