Abstract

The application of the Sliding Mode Thermal Control to dryer station furnace facility in agriculture productions is proposed. An adaptive controller is designed based on results obtained in the sphere of discontinuous system design. The derived Sliding Mode (SM) control algorithm written in Lab View environment should improve the control performance of the important characteristic of system such as thermal field of the oven. The proposed controller consists of the following blocks: sliding mode indicator to determine the occurrence of SM; observer block, to identify the state vector of the system, and the input delay compensation bloc.
