DigitalCtrl is a digital control algorithm library designed to simplify the programming of digital closed-loop controllers based on microcontrollers, DSPs, and processors, and to provide closed-loop controller algorithms with optimized performance and space optimization. The current version implements the PID/PI controller function and will support various derivative PID algorithms in the future, including integral limiter PID, weighted average PID, and highly optimized PID for low-frequency MCUs.

DigitalCtrl 是一个数字控制算法库，目的是简化基于单片机、DSP、处理器的数字闭环控制器的程序设计，提供性能优化、空间优化的闭环控制器算法。目前版本实现 PID/PI 控制器功能，未来将支持各类派生 PID 算法，包括积分限幅 PID、加权平均 PID、用于低主频 MCU 的高度优化 PID 等。
