Description: 摩托车仪表有速度表、里程表、测量计，还有显示发动机轴转速的仪表。目前，这些仪表都是指针式的，并且相互独立，存在精度低、成本高、不直观等缺点。随着微控制器技术的发展，仪器仪表的小型化、数字化、智能化已成为一种发展趋势，因此我们提出摩托车车载仪表数字式设计的设想，该仪表具有过速、油量不足、酒后开车、自动点亮、关键参数存储等自动报警功能。对抗干扰、抗震动有一定的要求。-Motorcycle Meter with speedometer, odometer, gauges, as well as display the engine shaft speed meter. Currently, these instruments are the pointer, and independent of each other, there is low precision, high cost, non-intuitive shortcoming. With the development of micro-controller technology, instrumentation miniaturization, digitization, intelligence has become a trend, so we raise motorcycle-car design vision of digital meter, the meter has been growing too fast, not enough fuel, alcohol After the drive, automatic light, the key parameter storage automatic alerting capabilities. Pairs of anti-jamming, anti-vibration have certain requirements.

Description: Paper about Induction motor drive based on direct torque control (DTC) which allows high dynamic performance to be obtained with very simple hysteresis control scheme. Direct control of the torque and flux is achieved by proper selection of inverter voltage space vector through a lookup table. In this paper apart from six sector look up
table used for classical DTC, a modified look up table, which also use six sectors but with different zones and a twelve sector table are presented.

-Abstract: As the stepper motor drive system has nonlinear characteristics, which make use of simple fuzzy control with traditional PID control accuracy is not high, so this paper proposes to use fuzzy PID controller of the stepper motor drive system control, fuzzy PID controller was designed. At first the mathematical model of the stepping motor, and derived a mathematical model and its transfer function then describes the structure of fuzzy PID controller, and fuzzy control rule generation method, and digital simulation of the control program. Simulation results show that: the method to adjust the high accuracy, fast dynamic response, no overshoot, there is certainly feasible.

Description: 本课题设计了一款用于两相混合式步进电机的驱动芯片，内部集成了PWM(脉
冲宽度调制)斩波控制和步进电机细分驱动功能，工作于36V并可持续输出1.5A
电流。PWM电流控制电路与3位非线性数模转换器相结合，可细分电机绕组上的
电流，对步进电机进行整步、半步、1/4步或1/8步的细分控制，从而实现了步
进电机不同步距角的运作。为了改善电机性能，特别是电机工作在微步距模式下
的正弦电流波形下时，芯片可提供三种不同的电流衰减模式（快衰减模式、慢衰
减模式、混合衰减模式）。同时，芯片内部的保护电路可实现过热关断和欠压锁
