Control of greenhouse with parabolic trough collectors

Abstract : Resource management in nowadays agriculture imposes the use of newtechnological solutions for automation and energy efficiency and this paperconcentrates on the control of internal temperature of a greenhouse using parabolictrough collectors (GHPTC) for internal heating. The actuator for the GHPTCcontrol system is the conducting fluid pump that enables the liquid flow into thecollector pipes. Both the nonlinear and linear models are presented in the paper inorder to tune a classical controller. A comparison of controller performances(stationary and transient) was conducted by simulation, using Matlab/Simulinksoftware. Also, the gradient descent method was applied for an optimal tuning of thetemperature controller, imposing minimum overshoot.
