| Abstract: | This paper proposed a multivariable optimum control strategy for the thermionic heater with the features of not reguiring any dynamic model and Oxygen analizer. The fuel flow rate is controlled on the rule of heat balance. The coefficient for excess air is controlled by the self-searching optimum control strategy to obtain the highest calorific efficiency. A constrained burning region control loop with dynamic feed forward compensation of air flow rate is used for the burning system of heater to resist various interferences and to maintain the heater at best burning status for a long time. This control strategy has been used in the heaters with the efficiency increased by 2%. |
