Design a Greenhouses Temperature Control System

Abstract

Greenhouse temperature is a critical factor in quantity of the agriculture production. Sudanese greenhouse use primary temperature control methods. In this paper greenhouse temperature adaptive control simulated using self-tuning proportional –integral- derivate controller (PID) use pole placement approach. The temperature degrees simulated by the adaptive control system of the greenhouse chosen based on Rehab’s model [1] which determines the temperature degrees for best growing. In this work both the open-loop system and adaptive close loop simulated and compared. The results showed that the adaptive system reduced the steady state error.
