Abstract

The application of the Sliding Mode Thermal Control System to laser spectroscopic system 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 should improve the control performance of the important characteristic of system such as thermal field of the oven. The suggested controller program written in LabView environment consists of the following blocks: the sliding mode indicator determining the occurrence of SM; the observer block, identifying the state vector of the system; the anticipatory compensation block. The obtained control algorithm is verified on the real system.
