AVR单片机定点计算函数说明及C源码。包括定点求解平方根和对数。还打包了一个外国网站上的Fixed Point Library。定将给开发工作带来极大的方便。(AVR single-chip fixed-point calculation function descriptions and C source code. Including fixed-point solution of the square root and logarithmic. Also packed a foreign site on the Fixed Point Library. Scheduled development work will bring great convenience.)

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. )
