基本策略。现有轨道检修车无法快速移至抢修点的弊端给线路检修、抢修带来困
难，因此改善现有轨道检修车，设计出一种能在轨道与站台间快速转换的陆轨两
用车已成为一项崭新课题。本文研究的陆轨两用电动汽车驱动控制系统是陆轨两
用车的关键，对于整车的顺利开发和可靠使用具有重要意义。
本文首先介绍了我国以及世界主要城市轨道交通发展现状，本课题的研究背

定选用无刷直流电机作为陆轨两用车的主驱动电机。
其次介绍了无刷直流电机的基本结构，阐述了无刷直流电机的工作原理并建
立了其数学模型，确定其调速控制策略，对无刷直流电机的双闭环控制系统采用
模糊自适应 PI 控制，基于 Matlab/Simulink 平台，结合模糊自适应 PI 控制器设计，
组建了基于模糊自适应 PI 控制的无刷直流电机双闭环控制系统仿真模型，将利用
模糊自适应 PI 控制器和常规 PI 控制器的调速系统性能作了分析和比较。
最后从无刷直流电机控制系统的硬件组成出发，对以 DSP 为核心的控制回路
和以 IPM 为核心的主电路设计作了详细介绍，给出了系统硬件结构图和各个部分
的组成原理图，主要包括控制系统 DSP 的外围电路设计、IPM 电路设计、电压和
电流检测电路设计，转子位置检测电路设计以及监控显示电路设计。控制系统软
件设计主要由主程序和中断服务子程序组成，主程序主要完成 DSP 控制系统初始
化，中断服务程序主要设计了电流调节程序和速度模糊自适应 PI 调节程序。另外

ABSTRACT
As China's urban scale and the rapid development of economic construction, urban
population increased dramatically, urban traffic supply and demand becoming more
intense, so to develop rail transport services in major cities of China is a basic strategy
for achieving sustainable development. Existing rail maintenance repair car can not be
quickly moved to point of the shortcomings take difficult for the line maintenance and
repair ,therefor improving the existing rail maintenance vehicles, to design a site in the
track and the land can quickly convert between two rail cars has been as a new subject.
In this paper, the drive control system is the key of the land-rail dual intelligent vehicle,
is important for the smooth development and the reliability use of the vehicle.
First this paper describes the development of urban rail transport, the world's major
urban rail transport development status, the subject of the research’s background and
significance, for the drive motor characteristics and requirements of the electric vehicle
and the choice for the electric drive motor vehicles, choose the brushless DC motor as
the main drive motor for the two rail cars.
Second, mian introduces the mathematical model and the basic components of the
brushless DC motor, describes the working principle of the brushless DC motor,confirm
the control strategy and speed control method of the brushless DC motor: the brushless
DC motor using fuzzy adaptive PI control for the dual closed-loop control system. In
the Matlab / Simulink window to establish a brushless DC motor speed control system
simulation model, and combined with design content of the fuzzy adaptive PI controller,
built a brushless DC motor dual closed loop control system based on fuzzy adaptive PI
control, analysis of different response curves of the motor starting, running, under
sudden load changes, in final comparative analysis the performance comparison of the
adaptive PI controller using fuzzy controller and conventional PI speed control system.
Finally, from the hardware components of the brushless DC motor control system,
starting introduces in detailly the core of the control loop on the DSP and the core of the
IPM main circuit design, gives the system of the hardware structure and composition
and the principle map of the various parts, Details of the control system of DSP
peripheral circuit design, IPM circuit design, voltage and current sensing circuit design,
the rotor position circuit design and the detection control circuit design. The Control
system software design mainly composed of main program and interrupt service
routines, the main program mainly to complete DSP control system initialization, the
interrupt service routine the main design of the current reconciliation process and speed
blur adaptive PI controller program. Also briefly introduced the choice of battery of the
two land-rail vehicles and the introduction of the land-rail dual conversion system, and
the design of the corresponding hardware circuit.
