求出小车与黑线间的位置偏差，采用PID 方式对舵机转向进行反馈控制。通过
自制的速度传感器实时获取小车速度，采用Bang-Bang 控制策略形成速度闭环
控制。小车还将通过特定算法分析出前方的路况，并根据路况的不同而为小车
分配以不同的速度。文中将介绍赛车机械结构和调整方法，赛车转向模块和驱
动模块的设计、参数和有关测试，图像采样模块的摄像头工作机制以及安装选

abstract the black line on the contest lane by edge-detection method and calculate
the position difference between the vehicle and the black line with which we will
have a PID feedback control on the steering angle. The vehicle also uses a
speed-sensor made by ourselves to obtain the real time speed which will be used in a
speed feedback that adopts Bang-Bang control method. Certain algorithm will be
employed to analyze the lane styles in front of the vehicle and set different vehicle

Description: 步进电机是将电脉冲信号转变为角位移或线位移的开环控制元件。在非超载的情况下，电机的转速、
停止的位置只取决于脉冲信号的频率和脉冲数，而不受负载变化的影响，即给电机加一个脉冲信号，电机
则转过一个步距角。这一线性关系的存在，加上步进电机只有周期性的误差而无累积误差等特点。使得在
速度、位置等控制领域用步进电机来控制变的非常的简单。为此， 51测试网在腾龙开发套件中首次引入
了步进电机技术，方便用户应用掌握。-Stepper motor is the electrical pulse signal into an angular displacement or linear displacement of the open-loop control components. In the case of non-overloaded, the motor speed, and stop depending on the location of only the frequency of pulses and pulse a few, and not subject to the impact of changes in load, that is, to add an electrical pulse signal, a step motor is turned angle. The existence of this linear relationship, together with the stepper motor without error only cyclical characteristics of the accumulated error. Made in terms of speed, position control, such as stepper motor to control the use of very simple changes. To this end, the 51 test network development kit Tenglong first introduced the stepper motor technology, applications and user-friendly hands.

Description: This book is intended to be an exposition of the modeling and control of
electric machines, specifically, the direct current (DC) machine and the
alternating current (AC) machines consisting of the induction motor, the
permanent magnet (PM) synchronous motor, and the brushless DC motor.
The particular emphasis here is on techniques used for high-performance
applications, that is, applications that require both rapid and precise control
of position, speed, and/or torque. Traditionally, DC motors were reserved
for high-performance applications (positioning systems, rolling mills,
traction drives, etc.) because of their relative ease of control compared to
AC machines. However, with the advances in control methods, computing
capability, and power electronics, AC motors continue to replace DC motors
in high-performance applications. The intent here is to carefully derive
the mathematical models of the AC machines and show how these mathematical
models are used to design control algorithms
