【摘要】 电励磁双凸极电机是一种新型交流无刷电机，它具有简单的结构、高可靠性、较高的能量密度和高速运行能力。将DSP技术应用于双凸极电机的控制不仅简化了系统的硬件结构，还可以实现各种优化控制方法。 本文首先简要介绍了电励磁双凸极电机的结构、数学模型以及电动和发电工作的原理。在此基础上提出了用Pspice软件建立双凸极电机电动和发电系统的仿真模型的方法。由于双凸极电机电动工作时需要知道转子位置角，并根据转子位置角来确定电机定子各相绕组通电顺序和变换器功率管工作时间，本文介绍了角度控制与电机转向的关系，并对基于全桥变换器的双凸极电动机换相角与相电流及输出转矩的关系进行了理论分析和仿真验证，提出了优化双凸极电机换相角的方法。 本文还分别介绍了基于DSP的双凸极电机电动和发电系统的软硬件实现。其中，电动系统主要介绍了实现电机的转速、电流双闭环以及换相角优化控制的方法。发电控制系统主要介绍了一种具有自检功能的双凸极电机调压器的软硬件设计方法。 最后，分别对电励磁双凸极电机电动控制器和发电机调压器试验验证系统进行了实验，实验结果表明两个系统都具有良好的性能，验证了理论分析和数字仿真以及系统软、硬件设计的正确性。更多还原

【Abstract】 Doubly Salient Electro-Magnetic Motor is a relatively new type of AC brushless machine, which offers an excellent balance between cost, reliability, power density, and high-speed capability. The use of Digital Signal Processor (DSP) controller simplifies the control system, and makes it possible to implement optimized control algorithms.First, this thesis introduces the basic structure, static characteristic, operation principle of Doubly Salient Electro-Magnetic Motor and Generator. Then the thesis introduces the modeling of Doubly Salient Electro-Magnetic Motor and Generator using Pspice. Rotor position must be known to determine the working sequence of each phase and the time they works. Angle-control affects the direction of the motor. It also affects the current waveforms in windings and then affects the torque. This thesis analyzes the angle-control theory and proposes a way to find the optimized angle. Simulation is performed to verify the results.This thesis introduces the hardware and software design of the digital control system of Doubly Salient Electro-Magnetic Motor, which mainly discusses the speed and current loops and angle optimization control. The design of a digital voltage regulator with Built-in-Test function using Doubly Salient Electro-Magnetic Generator is also introduced.Prototypes of Doubly Salient Electro-Magnetic Motor and Generator control system is set up. The experiment results are obtained on the prototypes, which prove that the theories and analysis are correct.更多还原
