An integrated-starter-generator (ISG) system provides a cheap hybrid power strategy for hybrid electric vehicles (HEV). 12-10 flux switching integrated-starter-generator (FSISG) is one type of ISG machine, which employs the flux switching topological structure to improve the performance. In this paper, a prototype of 12-10 FSISG with the improved structure, which was employed to improve the manufacturability, was analyzed and studied. Through numerical studies, the influences of the improved structure and the characteristics of 12-10 FSISG were revealed. According to finite element analysis (FEA) results, the output voltage of FSISG can be considered as sinusoidal voltage. The results of the output torque show that the excitation current density of FSISG should be limited to less than 9 A/mm2 to avoid serious magnetic saturation. Next, the experimental tests of the prototype were carried out on the testing platform. In generating mode, the experiment results indicate that FSISG can output electrical energy with high efficiency in wide speed and torque ranges. In starting mode, the maximum starting torque of the prototype is 10.5 Nm. During the starting procedure, the prototype reaches a steady state rapidly. In the variable load conditions, it shows a rapid response ability to the changes of loads. According to the experiment results in this paper, the 12-10 FSISG has shown a promising performance for HEV application in both generating mode and starting mode.

“…The traditional PID control is a linear controller, which can control the input quantity by the linear adjustment of the proportion, integral and differential, so as to output the appropriate output quantity. For nonlinear systems such as PMSM, the control effect of the traditional PID control in many cases is not ideal, and it needs to be repeated debugging to get the appropriate PID value [8,9]. Single neuron adaptive PID controller is introduced in this paper, and the new PID controller based on intelligent control can adapt to the nonlinear system.…”

Permanent Magnet Synchronous Motor (PMSM) has been widely used in many fields for its advantages of small size, high efficiency, simple structure and low noise. In order to further improve performance of PMSM, it is necessary to do further research of its control strategy. Therefore, this paper mainly studied the direct torque control (DTC) strategy and its improved algorithm of PMSM. In this paper, we first introduce the mathematical model of PMSM and the zero vectors DTC, and then compares the traditional PID controller and the new adaptive PID controller. In order to better explain the problem, this paper makes a comparative simulation of the traditional DTC and the zero vectors DTC and the simulation results are shown in figure 1-8. By analyzing the results, we can find that the simulation that the flux waveform, three phase current waveform, the electromagnetic torque waveform, the speed waveform and the pulse of the DTC control with zero vectors have been improved obviously. In response time, the two can respond more quickly. So, this fully proves the superiority of the zero vector DTC control. And at the same time, we make a comparative simulation of the traditional PID control and the new PID control, and the simulation results are shown in figure 8-Figure 11. By analyzing and comparing the simulation results, we can find that the torque and speed pulse of the new adaptive PID controller is smaller, and its response time is shorter, and its anti-interference ability is stronger, and the steady state performance of the motor is improved remarkably.

An axial flux permanent magnet motor (AFPMM) is a permanent magnet motor with a novel structure, equipped with higher efficiency and torque density than a traditional radial flux motor. In this paper, a position tracking controller based on fuzzy sliding mode control is presented and applied to an AFPMM servo system. High torque capability at a relatively low and large speed range is achieved. Fuzzy sliding mode control weakens chattering in sliding mode control, and helps the system meet the requirement for high accuracy in servo system. A simulation model is constructed based on a Matlab/Simulink platform. The numerical results confirm that the proposed control system can track given signals accurately with desired control performance.
