We design vortex control algorithms for an electromagnetic suspension in the keeper position tracking problem. The main feature of these vortex algorithms concerns the invariance property with respect to unmatched external disturbances of a wide class. It is shown that the suggested algorithms guarantee the closed-loop stability under uncertain parameters of the electromagnetic suspension (mass, electrical...
The new control algorithms for wide class of electromechanical systems are proposed on the base of discontinuous control in the paper. The designed vortex algorithms provide full invariance of the closed loop system with respect to unmeasured unmatched disturbances. The efficiency of the proposed algorithms is demonstrated on the base of DC motor control.
The design algorithms of closed loop control system for surface profile measurement device are proposed. Control inputs are used to construct closed loop system, which oriented on identification of desired parameter that is identified by sliding mode observer then. As a result, the designed nonlinear system has high selective properties with respect to registered value. It is shown by computer simulation...
