摘要
为了适应机载电气系统结构的日益复杂变化,保证电气系统性能的良好性,降低飞行试验的风险,提出了一种机载电气系统半实物仿真方法。以无刷直流电机(brushless DC motor,BLCDM)伺服系统为研究对象,按照RT-LAB建模规则,搭建了系统仿真模型;设计了以DSP(TMS320F28335)为核心的电动机控制电路和信号调理电路;在CCS3.3开发环境下,完成了电机控制软件的设计。在此平台上,对该伺服系统进行了突加负载和突加给定转速的动态性能仿真,并与全数字仿真的结果进行了对比分析,验证了半实物仿真方法的有效性和准确性。
In order to adapt to the increasingly complex changes of the airborne electrical system structure,ensure that the electrical performance of the system is well,reduce the risk of flight test,this paper puts forward a kind of airborne electrical system hardware-in-the-loop simulation method.This paper uses the semi-physical simulation platform RTLAB to study brushless DC motor（BLDCM）servo system.According to the RT-LAB modeling rules,the model of the motor was put up.The controller of the motor,which takes DSP TMS320F28335 as the core,and signal conditioning circuit were implemented.The control program was accomplished in CCS3.3 Hardware-in-the-loop simulation experiments were carried out to simulate the serve system＇s dynamic performances.The dynamic response of the motor could be simulated by changing the load torque and the speed settings.Compared with digital simulation and real-time simulation,the validity and accuracy of hardware-in-the-loop simulation were confirmed.
