华勒斯树结构的8位修正展位乘数

costas载波恢复算法 锁相环路，注释很清楚(costas carrier recovery algorithm PLL)

这是我毕业设计做的一个SVPWM同步永磁交流电机的控制系统，里面除了一个SVPWM的驱动算法之外，还有一个步进电机的控制器，以及基于QUARTUS7.2的NIOS II控制核心，通过PC的串口可以控制同步永磁交流电机和步进电机进行精确的定位。该系统较复杂，运用的知识也比较多，在SVPWM算法，PID算法，步进电机控制方面，NIOS II的串口编程等都有值得参考的地方。最好使用QUARTUS7.2编译，目标芯片是选用EP1C6Q240-This is my graduation project SVPWM make a permanent magnet AC synchronous motor control system, which apart from a driver SVPWM algorithm, there is a stepper motor controller, as well as QUARTUS7.2 based on the NIOS II control core, through PC serial port can be controlled permanent magnet AC synchronous motor and stepper motor for accurate positioning. The system is more complicated, the use of more knowledge, in the SVPWM algorithm, PID algorithm, stepper motor control, NIOS II serial programming, such as places are worth considering. QUARTUS7.2 compile the best use of the target chip is optional EP1C6Q240
