In this paper the problem of vibration reduction is considered. Generally, mechanical vibra-
tions occurring during the operation of a system are undesirable and may have a negative
effect on its reliability. A finite element model of a single active blade is developed using the
Abaqus software. This structure consists of a multi-layer glass-epoxy composite beam with
an embedded macro fiber composite (MFC) piezoelectric actuator. For vibration control the
use of a positive position feedback (PPF) controller is proposed. To include the PPF control-
ler in the Abaqus software, a special subroutine is created. The developed control algorithm
code makes it possible to solve an additional differential equation by the fourth order Runge-
Kutta method. A numerical dynamic analysis is performed by the implicit procedure. The
beam responses with and without controller activation are compared. The control subsystem
model also includes the hysteresis phenomenon of the piezoelectric actuator. Numerical
findings regarding the PPF controller’s effectiveness are verified experimentally
