：针对电动汽车永磁同步电机无位置传感器控制系统，在两相静止坐标系( —B)内将滑模观测器法 与MRAS结合，提出了基于模型参考自适应的滑模观测器，并利用自适应律估计永磁同步电机的转子速度。仿真 和试验表明无位置传感器控制方法是切实可行的。 关键词：电动汽车永磁同步电机无位置传感器控制 自适应滑模观测器(This paper presents a new adaptive slid—mode observer for electric vehicle permanent magnet synchronous motor(PMSM)sensorless control system，which is combined with the sliding mode observer and model reference adaptive method in the two—phase stationary reference frame． The speed of PMSM rotor is estimated by adaptive law．Simulation and experimental results show that the sensol ]ess control method is practical and feasible。 Key words：EV PMSM position sensor]ess control ASMO(adaptive slid—mode observer))

说明：  KEIL C51，51单片机实现MODBUS从机端(KEIL C51, 51 single-chip client realize MODBUS slave)

说明：  使用了成品遥控车的遥控与接受模块，基于STC89C52RC,模拟PWM输出控制车速，五个前进挡，两个倒挡(The remote control and acceptance module of the finished remote control vehicle is used. Based on STC89C52RC, the output of PWM is simulated to control the speed of the vehicle. There are five forward gears and two reverse gears.)

A nice spaceshooter/space-travelling game written in tasm. You can buy and trade items, upgrade your ship, land on different planets and space stations, fight with space pirates in a huge map that is full with objects, asteroids, ship wrecks and others. In this version you start with more than enough money and if you die the game doesn t stop but your screen becomes a little "messy" (guys, this game remained in beta state :-) IMPORTANT: In game help is avaible if you press F1! It is really needed because I won t tell you here how to control the ship or access the world map! Btw there is a read.me file too, about some technical stuff if you want to know some interesting things...
