摘　　要：为提升船用异步电机的控制性能,提出基于数字信号处理器的船用异步电机矢量控制方法。选取TMS320F28335型单片机,作为船用异步电机矢量控制的数字信号处理器,处理矢量控制的全部数字与算法。设定转速指令值与相应转子磁链值作为矢量控制输入值,依据转速估算值与转速指令值的差值,获取下一指令周期的电磁转矩输入值,电磁转矩输入值与电磁转矩反馈值之差设置为转矩调节器的输入值,获取电压矢量的转矩分量指令值。利用数字信号处理器运行PI控制算法完成转速估计、转矩调节以及磁链调节,实现船用异步电机磁通电流、转速以及转矩的闭环控制。实验结果表明,该方法利用数字信号处理器实现船用异步电机定子电流、转矩与转速的高效控制,船用异步电机在添加负载时,定子电流可在0.5 s内恢复稳定。The vector control method of Marine asynchronous motor based on digital signal processor is studied to improve the control performance of marine asynchronous motor. TMS320F28335 single chip microcomputer is selected as the digital signal processor for vector control of marine asynchronous motor to deal with all the digital and algorithm of vector control. Set value and the corresponding rotational speed rotor flux values as vector control input values, according to estimate speed and the rotational speed value of the difference, for the next instruction cycle electromagnetic torque input values,electromagnetic torque input value and the value is set to the difference between the electromagnetic torque feedback input value of the torque controller and obtain torque component of the voltage vector instruction value. The digital signal processor is used to run PI control algorithm to complete speed estimation, torque regulation and flux regulation, and realize the closed-loop control of magnetic current current, speed and torque of marine asynchronous motor. The experimental results show that the method can control the stator current, torque and speed of the marine asynchronous motor efficiently by using digital signal processor, and the stator current can be stabilized within 0.5 s when the marine asynchronous motor is loaded.
