Comparative study for enhanced temperature control in smart greenhouses

Abstract

This paper introduces a comparative study of four distinct controllers intended for efficient temperature regulation in smart greenhouses. Beginning with an overview of the general research background, the paper addresses the specific challenges inherent in greenhouse temperature control, as well as the different techniques used for regulation. Utilizing Matlab Simulink software, the greenhouse temperature control system is simulated. The study evaluates the performance of each controller in maintaining the internal temperature within the desired range amidst varying external conditions. Previous research has shown that all four controllers effectively maintain the desired temperature range, although their performance varies in terms of power consumption, precision, robustness, and response time, depending primarily on the project requirements and goals. Our contribution primarily consists of studying all these types of controllers and determining the best controller to choose for regulating the internal temperature of the greenhouse.
