PLATE HEAT-EXCHANGER TEMPERATURE COMPUTER CONTROL-SYSTEM

The observed stochastical disturbances occur frequently in temperature control systems composed of plate heat exchanger which is widely used in brewing industry. In reference to this disturbances the heat flow equivalent is widely introduced and the plate heat exchanger temperatu re computer control system with the real-time disturbance compensation is designed. Hereby the related control parameters are detected on-li ne and the incompletely differential PID is adopted as control algorit hm. The results of computer emulations show clearly that the new desig ned method can completely compensate the real-time disturbances and ha s therefore higher applied value in chemical industry and light indust ry.
