MODEL BASED DESIGN OF OPTIMAL MULTIVARIABLE CLIMATE CONTROL SYSTEMS

E.J. van Henten
The simulation results are presented of the application of the linear quadratic performance (LQP) control design methodology to a non-linear physical greenhouse climate system. A multivariable greenhouse climate model designed by Bot (1983) is used for controller design and evaluation. First, the non-linear model is linearised around a nominal working point. Then, a LQP controller is designed for the linearized system. Computer simulations, using the original non-linear system equations as pilot plant, demonstrate a very accurate controller behaviour compared to a control algorithm which is used in practice.
