【Abstract】 This paper discusses the controller based on compound fuzzy control algorithm. Because temperature in each room of the infrared reflow soldering machine is changeable and complex, it is difficult to control the output power of infrared heater. The result can be improved through a compound control method that is composed of fuzzy control algorithm and Ziegler Nichols control algorithm. It has been proved in practice that the system has excellent control effect.更多还原
