Abstract

Doubly salient electro-magnetic machine using traditional control method has large torque ripple for dead-time during commutation process and its special structure. During commutation, electro-magnetic torque and power will decrease quickly due to all switches are off states. In order to avoid the problem, a novel phase-shifted and interleaved angel control strategy was proposed in this paper. The control algorithm can eliminate dead-time and shape phase current of electric machine to improve output power and reduce torque ripple by adjusting phase-shifted angle and interleaved angle. In this paper, the mathematical model of the machine and working principle of the control strategy were described in detail. Moreover, phase-shifted and interleaved angle optimum method based on low torque ripple and large output power was also given. Finally, a “field-circuit” co-simulation model of motor driving system based on novel control method was built by electro-magnetic finite element analysis and transient solver of control circuit, and simulation results verify theory analysis.

双凸极电机的移相交错角度控制

采用传统控制方法的双凸极电磁电机在换相过程中存在转矩脉动大、死区时间长、结构特殊等问题。在换向过程中，由于所有开关都处于关断状态，电磁转矩和功率会迅速下降。为了避免这一问题，本文提出了一种新的相移交错角度控制策略。该控制算法通过调节相移角和交错角，消除电机的死区时间，形成电机的相电流，提高电机输出功率，减小转矩脉动。文中详细介绍了机床的数学模型和控制策略的工作原理。提出了基于低转矩脉动和大输出功率的相移交错角优化方法。最后，通过电磁有限元分析和控制电路暂态求解，建立了基于新型控制方法的电机驱动系统“场路”联合仿真模型，仿真结果验证了理论分析。
