-Modeling and control of radial force in the double stator type bearingless switched reluctance motor (BLSRM) is researched. The rotational torque is controlled independently from the radial force control. And the radial force is constant which is independent from the rotor position. In order to realize steady suspension, analytical models of torque and radial force for the proposed structure are derived. Meanwhile, in order to realize steady suspension, control scheme for proposed BLSRM is proposed. In the control method, the radial force can be controlled in arbitrary direction and magnitude by selecting some combinations of radial force windings. The validities of structure and control method are verified by the experimental results.

“…Self tuning mechanism of PID controller has been applied for controlling the position and shaping in actuators and simulations for this self tuned fuzzy PID controller on the servo motor presented in [16][17]. For the bearing less SRM, the design of hybrid stator and enhancement of electromagnetic forces has been presented in [18][19][20][21]. Due to the absence of proper tuning methods for conventional PID gains, researchers have been focused on design and implementation of widespread and easy methods in order to tuning the controller gains.…”

This paper presents a hybrid intelligent and design in a real time for the rapid prototyping of a robust fuzzy controller along with conventional Proportional-Integral and Derivative (PID) controller that allows quick insight of these integrated designs. The design procedure of the parallel fuzzy PID and its combination with the traditional PID in a universal control scheme are extended. The structural design of the parallel fuzzy PID controller is composed of three fuzzy sub controllers which are connected in parallel. These parallel sub controllers are assembled to get the proposed parallel fuzzy type PID controller. The hybrid fuzzy PID gains are expressed in the error domain. Hence, the structural design presents an alternative to control schemes employed so far. This hybrid intelligent controller is formulated and executed in real world hardware for position as well as speed control of a Hybrid Pole Self Bearing Switched Reluctance Motor (HPSBSRM) drive system. The design of the parallel fuzzy PID controller, implementation and finally analysis all are carried out using MATLAB/Simulink environment. Software results concluded that the novel hybrid intelligent parallel fuzzy PID controller generates better control action when compared to traditional PID controller, predominantly in system nonlinearities and in external load variations.

“…So far, there are two kinds of winding topologies. One is that there are two separated groups of three-phase windings embedded in the stator slots: one group for torque driving and one group for self-levitation [7]- [12]. However, since the additional suspension windings are wound on the stator core with the torque windings, it has larger size of outer diameter as compared to the conventional motor with mechanical bearings.…”

In this paper, a seven-phase inset-type permanent magnetic bearingless motor is proposed with characters as the treble frequency suspension force compensation and elimination of the affection of the third plane to the suspension plane. The winding configuration and harmonic distribution are presented. Then, the analysis formulations of inductance and suspension force of the proposed motor are presented and verified by Finite Element Analysis (FEA). Furthermore, the control system is proposed based on the derived voltage model, torque model and suspension force model with the rotor eccentricity being considered. Finally, the Simulink simulation is provided on a prototype motor to verify the validity of the analysis.
