Abstract
This topic take the boiler in the gallbladder temperature as the controlled plant, uses the instrument control, introduced temperature control system's constitution, PID adjust its parameter the installation method, and feeds back through the temperature transmitting instrument real-time examination boiler's temperature gives the controller, constitutes the single return route temperature closed-loop control system. The industry uses the intelligent PID adjustment, determines the PID parameter through the thumb rule, causes the system when the setting value change, can steady achieve the stable state fast, and has carried on the confirmation through the experiment, has analyzed under the different control mode control rule and the different controller parameter system's characteristic. PID controls fast to the temperature, accurate, steady, the highly effective adjustment, enabled the system to achieve the best control effect. Finally gave back to the system to increase the water cycle installment, analyzed the water cycle to the system performance influence, the increase water cycle installment to improved system's control effect to play the good role.
