摘要
模拟式PID控制器由于受到电子器件延迟性及非线性的限制,其瞬态特性及稳定性较差。文中研究了数字式PID控制器的工作原理,提出了基于单片机的数字式PID控制器的设计方案。该设计方案具有结构简单、实时性强、线性控制的特点。
Transient performance and stability of analog PID controller are poor because of the electronic device delay and nonlinear constraints. The working principle of the digital PID controller is studied. The design scheme of digital PID controller is put forward based on single chip microcomputer. The design has the characteristics of simple structure, strong real-time, linear control.
