“…The impact of mechanical bearing on the reliability and maintenance of the electrical machines is typically severe [5], [6]. The active control of the radial forces in such machines could lead to significant improvement in terms of noise reduction and vibration dampening [2], [7]- [10]. It would also enable the compensation of external forces acting on the rotating structure such as unbalance magnetic pull (UMP), inertial forces and forces of other nature.…”

Abstract-Radial force control in electrical machines has been widely investigated for a variety of bearingless machines as well as for conventional structures featuring mechanical bearings. This work takes advantage of the spatial distribution of the winding sets within the stator structure in Multi-Sector Permanent Magnet machine towards achieving a controllable radial force. An alternative force control technique for Multi-Sector Permanent Magnet machines is presented. The mathematical model of the machine and the theoretical investigation of the force production principle are provided. A novel force control methodology based on the minimization of the copper losses is described and adopted to calculate the d-q axis current references. The predicted performances of the considered machine are benchmarked against Finite Element Analysis. Experimental validation of the proposed control strategy is presented focusing on the suppression of selected vibration frequencies for different rotational speeds.

“…In [12], a modified ADRC method was used in a 6-degree-of-freedom parallel platform and the platform could be driven to follow the given references well. Furthermore, the ADRC method has been used in magnetic rodless pneumatic cylinder [13], electromagnetic linear actuator [14], multimotor servomechanism [15] and magnetic bearing [16]. However, compared with the traditional ADRC method which is nonlinear, a linear active disturbance rejection control (LADRC) method has also been developed for controller design.…”

“…However, the ADRC method and the LADRC method both have more tuning parameters than the traditional PID method, while the appropriate controller parameters depend on the experiences of experts. Sometime, the number of the ADRC method parameters can be reduced to one or two [16,20]. To compare the traditional ADRC method and the LADRC method clearly, this paper does not reduce parameters.…”

SummaryThis article investigates the event‐triggered containment control problem for nonlinear multiagent systems with mismatched stochastic disturbances. A set of second‐order extended state observers (ESOs) is constructed to solve the problem of bounded stochastic disturbances. The observers are able to estimate the disturbances in each control input channel in real‐time and solve the problem of stochastic disturbances path non‐differentiability. Based on backstepping technique, adaptive controllers are designed to ensure that the output of the followers converge to the convex hull formed by the leaders. Moreover, a simplified event‐triggered threshold condition is designed, which effectively reduces the update frequency of the controller and the complexity of threshold condition. Based on the Lyapunov stability theorem, it is proved that all signals in the closed‐loop systems are the practically bounded. Finally, the effectiveness of the proposed control scheme is verified by simulation results.
