Abstract—This paper proposes a multivariable digital control
design methodology for the voltage regulation of an islanded single
distributed generation (DG) unit microgrid and its dedicated load.
The controller design methodology is based on a family of spec
tral Multi-Input Multi-Output (MIMO) models of the microgrid
system and performs open-loop shaping and system decoupling si
multaneously by a convex optimization approach. The control de
sign procedure includes: (i) the determination of a family of non
parametric models of the system at various operating points, (ii)
the determination of the class of the controller, and (iii) system
open-loop shaping by convex minimizationof the summation of
the square second norm of the errors between the system open
loop transfer functions and a desired open-loop transfer function.
Based on the proposed design methodology, two -augmented
voltage controllers are proposed to regulate the load voltages of a
single-DG-unit microgrid. The proposed controllers guarantee the
robust stability and satisfactory dynamic response of the system in
spite of load parametric uncertainties and also the presence of non
linear load. This paper describes the theoretical aspects involved
in the design procedure of the controllers and evaluates the perfor
mance of the controllers based on simulation studies and experi
ments.
