The background system 1 calculates the real-time rotating speed of the engine through the operation model, converts the real-time rotating speed of the engine into a voltage value of 0-5V, and outputs the voltage value to the servo driver through the voltage analog quantity board card, and the servo driver controls the servo motor to rotate through PWM wave signals with corresponding proportional duty ratio, so that the rotating speed of the servo motor 64 is consistent with the calculated rotating speed of the engine. The transmission ratio of the first belt transmission 65 is 2: 1, the second belt drive 68 has a transmission ratio of 1: 1, the rotation speed of the crankshaft 62 is 2 times that of the camshaft 63, which is consistent with the rotation speed ratio of the crankshaft 62 and the camshaft 63 of a real high-speed machine. The Hall sensor is used for measuring a fluted disc, the sensor outputs a 24V high level signal when the teeth exist, the sensor outputs a 0V low level signal when the teeth do not exist, the speed measuring fluted disc rotates along with the shaft at the same speed, a square wave signal with the size of 24V can be obtained, and the square wave signal is input to the engine controller as an engine rotating speed signal.
In addition, the operation model output signal can represent a state signal of the diesel engine in general, such as the rotating speed, the rail pressure, the temperature and the pressure of each cylinder and the opening state of each valve of the diesel engine when the motor is the diesel engine. The controller obtains the state signal and then calculates according to the control program in the controller, and finally outputs a control signal, namely the output execution signal, part of the output execution signal is directly fed back to the operation model, the other part of the output execution signal acts on the external actuator and then enters the operation model, and the operation model receives the output execution signal and then operates again to update the state signal of the operation model, so that the operation and the control of the whole diesel engine are simulated by repeated circulation.
