Synergetic approach to control of axial left ventricular assist device rotor supported by magnetic bearings
Properties of nonlinear systems radically differ from linear in multivariance their behavior. In this regard, the control of such systems is a difficult task and has not been solved adequately problem of modern control theory. Methods of synergetic control theory (SCT) based on the idea of "nonload" impact on the system allow to create the objective control laws, which form the inner cooperative interactions between the processes of dynamic objects. The problem of the control of rotor supported by active magnetic bearings in artificial circulatory support device is presented in this paper. Because of strong nonlinear of the dynamical system the synergetic concept is apply for synthesis the effective control laws for the positioning of the pump rotor in the blood stream and provide the required parameters of the dynamics in terms of external disturbances to improve the efficiency of the artificial circulatory support device.
