摘　　要：永磁同步电机高效率、高功率密度、良好的转矩性能和易于控制等优点在工业自动化、汽车、航空航天、家用电器等领域发挥着重要作用。然而,在电气传动领域不仅需要精确地控制其运行状态,还需具备复杂的工业通信和人机接口。传统电气传动大多采用比例积分环节进行速度控制,会存在积分器饱和问题,扰动消失后,积分响应变慢;复杂的工业通信和人机接口需要占用大量的芯片资源和芯片IO,导致控制成本居高不下。通过对传统的比例积分器进行改进,引入输出前馈控制,解决由于积分器饱和带来的响应延迟,并通过改进外部通信协议和外部人机交互接口硬件电路,解决了传统传动系统设计只能通过增加芯片数量来解决资源和IO占用问题。改进后的系统可以在单芯片280039C DSP上完成全部功能,由于不存在芯片间通信,通信速率和响应速度都大幅提升,现场使用情况良好。Permanent magnet synchronous motors play an important role in industrial automation,automotive,aerospace,household appliances,and other fields due to their high efficiency,high power density,good torque performance,and ease of control.However,in the field of electrical transmission,it is not only necessary to accurately control its operating status,but also to have complex industrial communication and humanmachine interfaces.Traditional electrical drives mostly use proportional integral components for speed control,which may lead to integrator saturation issues,resulting in slower integration response after disturbance disappears.Complex industrial communication and human-machine interfaces require a large amount of chip resources and chip IO,resulting in high control costs.By improving the traditional proportional integrator and introducing output feedforward control,the response delay caused by integrator saturation was solved.By improving the external communication protocol and external human-machine interface hardware circuit,it solved the problem of resource and IO occupation that traditional transmission system design can only solve by increasing the number of chips.The improved system can complete all functions on a single chip 280039C DSP.Due to the absence of inter chip communication,the communication speed and response speed is greatly improved,and the on-site use is good.
