Research on Optimal Control of Greenhouse Temperature Based on Disturbance Observer

摘要：

　　Optimal control method of greenhouse temperature aimed at disturbances in the greenhouse environment system was proposed.Design a disturbance observer at first.In this section the focus was mainly on the selection of Q filters parameters.Then design a quadratic optimal output tracker on the basis of disturbance observer.Finally simulate and verify the designed optimal controller based on a simplified model of greenhouse temperature.The simulation results showed that the optimal controller has well disturbance attenuation and that the control output can follow the set value effectively satisfying the optimal index at the same time.
