\r\ncontrol of a rotary system powered by two permanent magnet DC
\r\n(PMDC) motors is proposed, where this system is mounted on an
\r\noscillatory frame. To achieve vibration isolation for this system,
\r\nactive damping and disturbance rejection (ADDR) technology
\r\nis presented which introduces a cooperation of a main and
\r\nan auxiliary PMDC, controlled by discrete-time sliding mode
\r\ncontrol (DTSMC) based schemes. The controller of the main
\r\nactuator tracks a desired position and the auxiliary actuator
\r\nsimultaneously isolates the induced vibration, as its controller
\r\nfollows a torque trend. To determine this torque trend, a
\r\ncombination of two algorithms is introduced by the ADDR
\r\ntechnology. The first torque-trend producing algorithm rejects
\r\nthe disturbance by counteracting the perturbation, estimated
\r\nusing a model-based observer. The second torque trend applies
\r\nactive variable damping to minimize the oscillation of the output
\r\nshaft. In this practice, the presented technology is implemented
\r\non a rotary system with a pendulum attached, mounted on a
\r\nlinear actuator simulating an oscillation-transmitting structure.
\r\nIn addition, the obtained results illustrate the functionality of the
\r\nproposed technology.","references":"[1] C. R. Fuller, S. J. Elliott, and P. A. Nelson, Active vibration\r\ncontrol. Academic Press, 1996.\r\n[2] R. E.
