-增:在`ev_io_start->fd_change` 中,如果发现 `anfds[fd]->active` �不为0,即需要监听 fd 的�某些事件,则添加 fd 到 fdchanges 中,fdchangescnt 加1。-删:在 `ev_run->fd_reify` 中,遍历 fdchanges 数组,对 fd 执行 `epoll_modify()`。遍历完 fdchanges 数组后,fdchangescnt 被设置为0。

As the motor operates, the voltage, current and position signals are sensed and fed back to the controller to modify the modulation of the inverter. One such feedback method is field oriented control (FOC), which uses two phases of current and the position to generate the proper vector of ...
