基于TMS320F2812的异步电机矢量控制系统

传统的矢量控制方法基于异步电机的稳态模型,控制性能受电机的参数影响很大。文章结合异步电机的特性和要求在控制策略中设计了转速,电流,磁链等多个闭环,采用了对参数依赖性很小的偏差电压解耦方式,并结合电机的电压模型和电流模型对传统的转子磁链计算进行了补偿和修正,有效地降低参数变化对系统的影响。DSP芯片TMS320F2812有着强大的运算能力和优良的控制性能,基于该芯片的硬件系统很好的实现了控制方案,实验表明该控制系统精度高,实时性和动态响应都较好。

Vector Control System for High-power Asynchronous Motor Base on TMS320F2812

The traditional vector control is based on steady-state model of asynchronous motor,the performance of the control system is affected greatly by motor parameters.Combining with the speciality of asynchronous motor,designed multi-closed loop of the rotational speed,current,and flux in control strategy according to the closed loop can resist to parameters variation,adopted deviation voltage decoupling which little depend on parameters,and compensated and corrected the conventional calculation of rotor flux,th...
