Abstract：ased on the analysis of the cascade control system of distillation column，the automatic temperature control system of distillation section is designed in the paper.In the control system，control variables，manipulated variables，actuators，controllers，process detection and control equipment are selected，and the block diagram of the temperature cascade control system in the distillation section is designed.On the MATLAB/Simulink simulation platform，the simulation and design are carried out to verify the correctness of the control strategy proposed in this paper.

Key words：distillation section;temperature;cascade control;the block diagram control
