Application of inverse system method for environment control in intelligent greenhouse

The control strategy of intelligent greenhouse environment was discussed. The system models are characterized by nonlinear, strong coupling and much disturbance variables. So the inverse system method was used decoupling and linearization of the system. On constructing inverse system compensated the influence of outside climate disturbing at same time. After linearization, PDF control method was integrated to optimize the system static and dynamic performances. The real output results and the simulation results were described. The steady-state performance and dynamic performance are content. So it is reasonable and successful to make use of the inverse system method in greenhouse environment control system.
