在计算机控制系统中,使用的是数字PID控制器,数字PID控制算法通常又分为位置式和增量式控制算法。由于计算机控制是一种采样控制,它只能根据采样时刻的偏差值计算控制量,因此模拟式中的积分和微分项不能直接使用,需要进行离散化处理。以一系列的采样时刻点kT代表连续时间t,以和式代替积分,以增量代替微分,作近似变换。采样周期足够短,才能保证有足够的精度-the computer control system, using the digital PID controller, digital PID c

虽然计算机控制技术已经产生,但是PLC控制因为它的高性能、成本低、并且对恶劣的环境有很强的适应能力而在工业控制的广泛应用中保持优势。而且,尽管硬件的价格在逐渐下跌,据估计,根据Frost和Sullivan对PLC市场的调查研究表明,每年销售硬件的价格要比销售PLC的价格(一千五百万)至少多出八十亿美元。PLC的创造者Richard E. Morley十分肯定的认为目前PLC市场是一个价值五十亿的工业-functional design. Programmable controller for t

此代码是遍历pc上usb设备。
包含控制器 hub port 设配id 等信息
usb其实和串口是一样的,其端口也是固定的(如果你不接扩展hub)。
有时一台电脑接多个相同的usb设备,如果接连个摄像头(前后各一个),我们如果区分打开的是哪一个呢?
1、先把usb设备先遍历出来,得到usb信息(设备串等)。
2、通过打开usb设备时返回信息(这个很重要 //usb#vid_1d27&pid_0600#5&10ef021e&0&5#{c3b5f022-5a42-1980-
