摘要
选取电压模型为基础,引入参考值补偿策略保证电机在低速运行时可准确测得转子转速。硬件方面设计了由双DSP控制板和两电平逆变器组成的电机控制系统。在TMS320LF2407A和TMS320VC33组成的双DSP控制板中,TMS320VC33的高浮点计算能力解决了编程和计算精度的问题,利用TMS320LF2407A自身的硬件特点实现快速通信、采样等功能。
Based on the voltage model ,reference value compensation strategy is introduced to estimate the accurate speed of the motor when it is in low speed.The hardware of motor control system is composed of dual-DSP control plate and two-level inverter.In the dual-DSP control plate, which composed with TMS320LF2407A and TMS320VC33. The programming and counting accuracy are solved by TMS320VC33 ,the fast communication and sampling are realized by TMS320LF2407A.
