摘　　要：在无刷直流电机控制系统的仿真中如何快速动态地求解无刷直流电机的状态方程组是一个关键问题。在Matlab/Simulink环境中,利用C语言形式的系统函数来构建仿真模块,可灵活快速地实现复杂系统的仿真建模。把系数矩阵放在静态变量存储区,可直接修改状态方程组的系数矩阵,达到快速修改此系数矩阵的目的。另外,在每个仿真步长的输出阶段修改系数矩阵,达到了动态更新的目的。仿真结果表明,文中所提方法可快速实现无刷直流电机控制系统的仿真,并可方便地用于验证无刷直流电动机的控制算法和策略。In control system simulation of brushless direct current motor, to solve state equations of the brushless direct current motor is a key issue. In Matlab/Simulink environment, using C language system functions to build simulation module can be flexible and can achieve fast simulation of complex system modeling. By putting the coefficient matrix in a static variable storage area, the coefficient matrix of the equation of state can be modified directly and quickly. Mean- while, during the output stage in each simulation step, modification of coefficient matrix can achieve the purpose of dynamically updating the matrix. The simulation results show that the proposed method can achieve fast simulation of brushless direct current motor control system, and can be easily used to validate the control algorithms and strategies of brushless direct current motor.
