Comparison between self-tuning fuzzy PID and classic PID controllers for greenhouse system

Abstract

This work develops a solution for greenhouse climate control employing a comparison between two controllers, the Fuzzy FID and the classic FID Knowing that the greenhouse model has a high strong coupling, a feedback-feedforward linearisation and decoupling method employing measured disturbances is used. Those proposed controllers are designed Very carefully. The comparison between those two controllers is made in terms of several performance criteria like settling time, peak overshoot, rise time. In addition to the responses due to step input. Results for various processes show that the Fuzzy FID using in those simulations has a perfect performances.
