Abstract

A solution to the problem of controlling the minimum temperature in greenhouses using controllers developed from nonlinear models of the system is discussed and applied on a real greenhouse. More precisely, the controllers designed are Takagi-Sugeno type controllers, and the proposed design method is an iterative method based on solving a set of Linear Matrix Inequalities, which ensures stability and performance in closed-loop. The tests in a real greenhouse show that it is possible to design controllers for control of nocturnal temperature that give good performance, and guarantee stability in a wide range of working conditions.
