A Novel Design of PI Current Controller for PMSG-based Wind Turbine Considering Transient Performance Specifications and Control Saturation
1 like51 views
The document presents a novel decoupled PI current controller design for PMSG-based wind turbines, enhancing transient performance under model uncertainty and control saturation. By integrating disturbance observer-based control with feedback linearization, the controller effectively maintains nominal performance recovery and includes an anti-windup compensator to address control saturation effects. Experimental validation demonstrates the controller's capability to achieve zero steady-state error while improving transient responses, offering a robust alternative for practitioners in designing current controllers for wind energy systems.

CONCLUSION:
This paper has presented a novel design of decoupled PI controller to enhance the transient
performance for the current control of PMSG-based wind turbine. The proposed controller
technique was established by combining a DOBC with feedback linearizing control law. It turns
out that the composite controller has a decoupled PI-like structure plus two additional parts. The
first part is basically an anti-windup compensator, while the second part uses the reference jump
information to cancels out the effect of the sudden step changes in the power demand on the
transient response. This modification of the decoupled PI controller permits to guarantee zero
steady-state error without sacrificing the nominal transient performance specified by the state
feedback controller. This salient feature cannot be achieved under the existing decoupled PI
controller, particularly when the model parameters are not accurate. Experimental tests have
been performed, and the results support the use of the reference jump information to improve the
transient performance under the decoupled PI controller. Therefore, the proposed approach
provides practitioners with an alternate method in designing a robust decoupled PI current
controller for PMSG-based wind energy conversion system.

Specifically, the design methodology consists of combining disturbance observer-based control (DOBC) with feedback linearization (FBL) technique to ensure nominal transient performance recovery under model uncertainty. By simplifying the DOBC under the feedback linearizing control, it is shown that the composite controller reduces to a decoupled PI current controller plus an additional term that has the main role of recovering the nominal transient performance of the feedback linearization, especially under step changes in the reference. Additionally, an anti windup compensator arises naturally into the controller when considering the control input saturation to design the DOBC. This permits to remove the effect of the saturation blocks required to limit the control input. The proposed control scheme is implemented and validated through experimentation conducted on 22-pole, 5 kW PMSG. The results revealed that the proposed technique can successfully achieve nominal performance recovery under model uncertainty as well as improved transient performances under control saturation.
