13. Speed and Axial Position Control for a Linear-Rotary Switched Reluctance Motor With Two Radial Windings

Author

He, Zhouhui, Cao, Xin, Chen, Huateng, Deng, Zhiquan, Hao, Zhenyang, Shi, Ruijie, and Meng, Xuying

Abstract

For 6/4 linear-rotary switched reluctance motors (LRSRMs), the magnetic-flux paths of the two windings are coupled in the radial direction, thus it is difficult to design the two-winding current algorithm for the linear and rotary control simultaneously. To solve this problem and achieve linear motion and rotation at the same time, speed and axial position control method is proposed by employing the equal magnetomotive force of two windings to calculate the given currents. This control method has the advantages of simple principle, easy implementation and can realize the coordinated control of rotation and linear motion. In addition, the mathematical model of LRSRM is established to facilitate the design of current algorithm. Simulation and various experiments are completed to verify the demonstrated performance of the proposed control method.

Abstract

A decoupling control strategy for the dual-stator winding induction generator (DWIG) system using space vector modulation (SVM) is described in this paper. The DWIG consists of a standard squirrel-cage rotor and a stator with two sets of 3-phase star-connected windings. The power winding feeds the load with DC voltage by the diode rectifier. The control-winding is fed from a static excitation controller (SEC), through which the output voltage of power-winding is regulated. Moreover, the control-winding can be designed for higher voltage than the power-winding to reduce the SEC current. It will help to reduce the power switch loss. The model of SEC is setup, based on which a de-coupler is introduced to get the fast control of d-q currents. The SVM is incorporated to produce the PWM signals. The nodal admittance method is presented to analyze the change rule of SEC during the wide- speed-range operation. An 18 kW DWIG system is provided to demonstrate the effectiveness and robustness of the proposed control strategy. dSPACE is employed to establish the rapid control prototype for the control strategy. Simulation and experimental results prove the effectiveness and good performance of DWIG system under the proposed control strategy.
