A scheme for temperature control of a greenhouse is presented. The present work uses an approach based on a combination of two different control schemes: Feedback Linearization (FL) and standard linear Model Predictive Control Since the methodology used for solving the prpblem generally leads to an optimization problem subject to state-dependent nonlinear constraints, an alternative for its implementation is discussed. Two control techniques are compared, namely MPC with FL and Nonlinear Model Predictive Control (NLMPC).
