摘  要:
针对拖拉机AMT(电控机械式自动变速箱)电控系统软件手工编程难度大、效率低、错误多等问题,基于Simulink/Embedded Coder提出了一种实现拖拉机AMT电控系统软件开发的方法。分析了拖拉机AMT自动换挡控制原理,利用Simulink工具箱建立了自动换挡控制算法模型,利用Embedded Coder工具箱搭建了以TMS320F28335浮点DSP(数字信号处理器)为处理器的拖拉机AMT控制系统模型,借助灵思创奇开发的仿真管理软件RT-SIM进行了快速控制原型半实物仿真,将自动生成的代码移植到目标板进行硬件在环半实物仿真。仿真结果表明,基于Simulink/Embedded Coder与RT-SIM开发的拖拉机AMT电控系统软件能够稳定运行,满足AMT系统的控制要求。

摘  要:
There are many problems in developing the traditional software such as massive work,low efficiency and many errors. To solve these problems,this article uses Simulink/Embedded Coder to develop tractor AMT control system software. The control theory of tractor AMT is introduced by the support of Simulink,the control algorithm model for tractor automatic shift is built. On the basis of Embedded Coder in Simulink,the DSP model for tractor AMT control system with TMS320 F28335 is designed. The rapid control prototype semi-physical simulation is accomplished by simulation management software RT-SIM developed by LINKS. The code for AMT control system is generated and loaded in the target board. As the hardware in the loop semi-physical simulation is accomplished,the simulation results verify the practicability of tractor AMT control system software development with Simulink/Embedded Coder and RT-SIM. The code developed by such method satisfies the control system requirements.
