摘要
永磁同步电机是典型的非线性系统,具有强耦合、多变量的特点,在汽车行业采用通用控制方法时面临复杂运行工况、恶劣工作环境等诸多挑战。为探索车用永磁电机控制策略及开发模式,通过分析永磁电机模型特点,提出了一种自适应最优弱磁控制算法,可实现电机在任意转速下尽可能扩大转矩输出范围并使电机电流最小。控制软件开发采用基于模型的设计方法,通过搭建Simulink模型,实现控制算法设计、仿真与测试一体化。运用代码自动生成方法将Simulink模型生成嵌入式代码,编译后下载到目标单片机上运行。选择TC234T-64F200N作为主控芯片,开发了控制器硬件平台。相关信号采集、驱动电路等设计及器件选型均符合汽车级标准。试验测试结果表明,文中所提出的算法和设计的控制器能实现良好的控制性能,具有较高的应用价值。
Permanent Magnet Synchronous Motor(PMSM) is a typical nonlinear system with strong coupling and multivariable characteristics.In the automotive industry,the general control method usually face many problems such as complex operating conditions and bad working environment.In order to explore the control strategy and development mode of vehicle permanent magnet motor,an adaptive optimal flux weakening control algorithm is proposed by analyzing the characteristics of permanent magnet motor model,which can maximize the torque output range and minimize the motor current at any speed.The model-based design method is adopted in the development of control software.By building Simulink model,the integration of control algorithm design,simulation and test is realized.The embedded code generated by Simulink model is compiled and downloaded to the target single-chip microcontroller by using the automatic code generation method.TC234T-64F200N is selected as the main control chip,and the hardware platform of the controller is developed.The design of relevant signal acquisition,driving circuit and device selection conform to the automobile grade standard.The test results show that the proposed algorithm and the designed controller can achieve good control performance and have high application value.
