摘要
舰船电机控制系统是一个典型的非线性系统,是舰船重要的动力转换装置,舰船电机控制系统的研究主要集中在控制方法优化和可靠性的研究方面,模糊控制、神经网路、遗传算法等非线性智能控制技术在舰船电机控制系统研究方面得到了广泛的应用,较好地提高了电机的工作效率和可靠性。但是当前的电机驱动系统不能进行故障监视,自诊断等,而且在追求大转矩情况下,多数舰船电机控制器依然采用大电压加绝缘栅双极型晶体管(Insulated Gate Bipolar Transistor,简称IGBT)来驱动电机,存在较大安全隐患。基于此,拟采用改进的弱磁控制算法,在数字信号处理器(DSP)硬件控制平台的基础上,采用额定电压为48 V的低压电机作为驱动电机,设计了一款舰船电机控制器及转子磁场定向矢量控制系统。经过实验验证,该系统安全可靠,舰船运行中转矩输出大,效率高。
The marine motor control system is a typical nonlinear system.It is an important power conversion device in ships.The research of marine motor control system mainly focuses on the optimization of control method and reliability.The nonlinear intelligent control technology such as fuzzy control,neural network,genetic algorithm has been widely used in the research of marine motor control system,which can improve the working efficiency and reliability of the motor.However,the current motor drive system can not carry out fault monitoring,self diagnosis and so on,and in the pursuit of high torque,most ship motor controllers still use high voltage and IGBT to drive the motor,which has great security risks.Based on this,an improved flux weakening control algorithm is proposed in this paper.On the basis of DSP hardware control platform,the low voltage motor with rated voltage of 48 V is used as the driving motor to design a marine motor controller and rotor field oriented vector control system.The experimental results show that the system is safe and reliable,the torque output is large and the efficiency is high.
