基于单片机的PID温度控制系统设计

介绍了一种基于M3单片机实现PID控制农作物大棚内温度的方法.针对单片机温度控制系统采用传统的单片机控制方法容易出现响应速度慢、算法简单、控制精度低等问题,采用将单片机和PID控制相结合的方法来控制温度.单片机造价低廉,当应用了模糊PID控制算法后,不仅满足高精度的控制温度调节,而且在很大程度上降低制造成本,具有极大实用意义.

This article introduces a method to realize PID control temperature in the greenhouse by using SCM M3.As SCM temperature control system using traditional SCM control method easily results in slow response speed,simple algorithm,low control precision,we adopt the method of combining SCM and PID control to control the temperature.The machine cost is low,and when the fuzzy PID control algorithm is applied,it not only meets the high precision control temperature regulation,but also reduces the manufacturing cost to a great extent,which is of great practical significance.
