说明：  基于zigbee技术CC2530 开发采集大气压(Development and Collection of Atmospheric Pressure Based on Zigbee Technology CC2530)

文以永磁同步电机为对象，采用矢量控制方案，首先我们研究了基于PI 的控制算法，在仿真基础上指出了PI 算法存在的一些不足。 在此基础上我们研究了基于扩张状态观测器（ESO）前馈补偿和线性比例反馈控制的永磁同步电机速度环控制算法， (Taking PMSM as the controlled plant, this paper studies the control system based on vector control, first, the servo control scheme based on PI control law is studied. Some limitations of PI based control scheme are pointed out. )

说明：  基于51单片机的ic卡门禁 有密码输入 ic卡登记 功能(Based on 51 single chip IC card entrance guard has password input function of IC card registration)
