And engine, and communicate connection industrial personal computer.
Wherein, industrial personal computer, as other embodiments, can also replace with other full as a kind of background controller
The controller of sufficient application demand.Throttle actuator is actually a kind of servo motor, and industrial personal computer passes through servo controller communication link
Connect the servo motor.Frequency converter uses CAN communication pattern, and industrial personal computer is communicated to connect by CAN cables and frequency converter CAN module,
Strong antijamming capability.Industrial personal computer uses NI LABVIEW Programming with Pascal Language, control instruction is sent out to frequency converter by CAN bus, by becoming
Frequency device controls motor.In addition, frequency converter, which also samples, connects the motor, for the actual speed of motor in real time, and
Collected motor actual speed signal is sent to industrial personal computer to show.In the present embodiment, specifically using encoder come
The rotating speed of motor is acquired, frequency converter sampling connects the encoder to obtain motor actual speed information.
Frequency converter realizes the closed-loop control to motor according to the control instruction of industrial personal computer and motor actual speed information,
Control motor can stable operation under permanent rotating speed pattern, realize the stability contorting of motor speed.The frequency converter is specially two quadrants
Frequency converter is connected with braking energy dead resistance and power supply, and the braking energy dead resistance and power supply are set respectively
In resistor box and power distribution cabinet, the energy for braking generation is consumed by the resistor box.In addition, frequency converter can also be carried to equipment
For defencive functions such as overcurrent, overvoltage, overloads, securely and reliably.
Specifically, when carrying out closed-loop control to motor, industrial personal computer sends control instruction to frequency converter, and frequency converter is according to this
Control instruction carries out rotating speed control to motor.Encoder detects the actual speed of motor in real time, and the motor detected is practical
Rotating speed is sent to frequency converter, by frequency converter according to closed-loop control of the real electrical machinery rotating speed realization to motor speed.
Industrial personal computer is communicatively coupled by modbus communication protocols with servo controller, for being sent to servo controller
Throttle position control instruction.The throttle position control instruction received is sent to throttle actuator by servo controller, to realize
Control to engine throttle opening.The practical accelerator open degree of engine is also fed back to industrial personal computer by throttle actuator, by industry control
