| 摘 要： | 提出一种基于二次型规划(QP)序列的内嵌式永磁同步电动机(IPMSM)控制系统的优化电流(保证电机运行损耗最小的d/q轴电流)的求解方法.首先,将IPMSM的效率优化建模为基于非线性约束的规划问题;然后,将非线约束的规划问题求解转化为线性约束的QP序列的求解.本文证明了QP序列解的收敛性、收敛值和IPMSM控制系统优化电流的近似同一性.仿真分析了该方法,其收敛度较快,且计算量较小,比较适用于IPMSM控制系统效率优的数字化控制.

| Abstract: | This paper proposes a method based on the quadratic programming (QP) sequence for solving optimization current , which ensure the minimal operation loss of the motor, of control system for interior permanent magnet synchronous motor (IPMSM) for electric vehicle. First of all, the efficiency optimization of IPMSM is modeled as the programming problem , and transformed it into linear constraint QP sequence. The convergence of QP series solution and the identity of the solution of the primal programming problem are proved ant it. By simulation analysis, the faster convergence, and a small amount of calculation, make it more suitable for the efficiency digital control of IPMSM control system. |
