Description: 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 control algorithm is usually divided into place - and incremental control algorithm. Computer control is a sample control, it can only be based on the time sampling error control volume terms, the analogue of integral and differential items not directly use, the need for discrete treatment. A series of sampling time point kT representatives consecutive time t, and - to replace integral to replace the differential increment for similar transformation. Sufficient short sampling period, in order to ensure a sufficient precision Platform: |

Description: 5.1 Control board project for sound system. Remote control, LCD, Encoder. I have almost no application with Arduino, I always tried to use Arduino alternatives and somehow found circuit solutions. But audio applications always intrigue me. I applied the digital volume control Arduino project made with Arduino Nano PT2323 and PT2322 audio control ICs, the circuit worked very well, and it is very good that it is remote control controlled, in addition, all controls can be made with a button encoder and 2 buttons.
