Problems solved by technology

Since aircraft generator sets are often used in very harsh industrial environments, they are often in variable working conditions. At this time, when ordinary PID control methods are applied to aircraft power generation control devices, the PID control parameters are fixed, and PID cannot be controlled in a random environment. The controller performs automatic correction, which reduces the control accuracy of the system, and it is difficult to meet the high control accuracy requirements of the aircraft
