摘要
分析了矢量转矩控制的基本原理和一些数学关系,从异步电机的数学模型入手,引入比例积分控制器,建立强鲁棒的状态观测器模型,计算电机转子磁链物理量。由于电动车电机控制算法计算量大,且实时性要求高,设计了由两片定点32位TMS320F2812组成的DSP控制电路。最后通过实验结果验证了该方案的有效性。
The basic principle and mathematical formulas of the vector control are analyzed.In order to calculate accurate motor rotor flux,mathematical model of induction motor is deduced by inserting proportion integral controllers,tate ob-server model is established,which has strongly robust.Owing to abundant computing information and strict real time request of control algorithm of motort,he DSP control circuit in this project is implemented by the integration of two TMS320F2812 DSPs.The experimental results show that the method is very effective.
