摘　　要：为解决内置式永磁同步发电机(IPMSG)在高速段出现的直交轴电流耦合问题,提出了一种新颖的基于单交轴电流调节器和电压矢量角相结合的弱磁控制算法。为满足发电机在全速段运行,需要判断发电机所处运行工况对最大转矩电流比控制算法(MTPA)和弱磁算法进行算法切换。发电机的直轴电流通过电流环和电压环的调节确定,故使得交轴电压的给定值可以根据输出电压和电磁转矩的变化而变化。这使得发电机的电流矢量始终能工作在最优点上,大大提高了发电机的效率和输出能力。此算法不需查表、不依赖于发电机参数且容易实现,经仿真和试验验证了该算法的可行性和稳定性。In order to solve the current coupling problem of the orthogonal axis in the high-speed section of IPMSG,a novel field weake-ning control algorithm based on the combination of single quadrature axis current regulator and voltage vector angle is proposed.In order to satisfy the generator running at full speed,it is necessary to determine the operating conditions of the generator to switch between the maximum torque current ratio control algorithm(MTPA)and the field weakening algorithm.The direct-axis current of the generator is determined through the adjustment of the current loop and the voltage loop,so that the given value of the quadrature-axis voltage can be changed according to changes in the output voltage and electromagnetic torque.This makes the current vector of the generator always work at its best advantage,greatly improving the efficiency and output capacity of the generator.This algorithm does not need to look up tables,does not depend on generator parameters and is easy to implement.Simulations and experiments have verified the feasibility and stability of the algorithm.
