Method and system for automatically controlling T45 temperature of turboshaft engine in ground test, equipment and storage medium

The invention discloses a method and system for automatically controlling the T45 temperature of a turboshaft engine in a ground test, equipment and a storage medium. According to the method, after the rotating speed of a fuel gas generator and the rotating speed of a power turbine of the turboshaft engine are both determined to be in a stable state, air entraining and power generation power double adjustment is started; the actual value of the T45 temperature is compared with the target value in the double-adjustment process, and the adjustment state of double adjustment is controlled at the same time according to the difference value between the actual value and the target value till the T45 temperature reaches the target value. According to the method, the characteristics of fast generation power regulation response and high bleed air regulation precision are combined, a dual-regulation control mode is adopted to realize that the turboshaft engine is quickly and accurately regulated to a target value at a
