In this embodiment, the actuator 110 is a device that drives the generator set to output a desired operating parameter under the control of the electronic governor 20. Specifically, the actuator 110 receives a drive signal transmitted from the electronic governor 20, operates in accordance with the drive signal, and outputs execution information in the operating state. The execution information is used to characterize the operating state of the actuator 110. For example, the actuator 110 of the present embodiment may include a dc motor, a transmission gear, an output shaft, and a feedback component. The actuator 110 is driven by a dc motor, the torque of which is transmitted to an output shaft via an intermediate gear.

Optionally, the control functions of the electronic governor 20 verified in the present embodiment include, but are not limited to, the control functions of the generator set such as shutdown, acceleration, deceleration, etc.
In this embodiment, the simulation model of the generator set is embedded in the simulation host 120 of the generator set, and the simulation model can simulate the body of the generator set and simulate the actual working parameters of the generator set, so that the control function of the electronic speed regulator 20 can be verified according to the actual working parameters, the electronic speed regulator 20 can be verified without occupying the generator set, and whether the control function of the electronic speed regulator 20 on the generator set is normal can be verified without occupying the generator set.

The simulation master 120 is also used to feed back actual operating parameters under an operation fault to the electronic governor 20 so that the electronic governor 20 adjusts the driving signal.
Specifically, the fault injection device 130 sends an operation fault signal to the simulation host 120, the simulation model of the simulation host 120 simulates an operation fault of the generator set, at this time, the simulation host 120 feeds back an actual working parameter under the operation fault to the electronic speed regulator 20, and the electronic speed regulator 20 can adjust the output driving signal according to the actual working parameter under the operation fault, so that the simulation host 120 can output a working parameter corresponding to an expected working parameter.
