摘要
介绍了数字PID的2种基本算法，并比较了其优劣，提出了抗干扰的PID改进算法．在此基础上，结合现代温室环境参数分级监控系统的设计实践，验证了改进PID算法的有效性．
Two kind basic digital PID methods are introduced, their disadvantages and advantages are compared. Then, an improved PID method is efficient to resist interference is proposed. Finally, the effectiveness of the improved PID control method is tested and verffied in combination with the design practice of modem greenhouse environment factors detection and control system.
