Electronic throttle control method and electronic throttle control device

An electronic throttle control device, comprising:

• a throttle to which an actuator is attached;
• and
• an electronic control unit that controls opening and closing of the throttle via the actuator while providing a control signal on a basis of an input data signal, wherein:
• the electronic control unit includes:
• a revolution speed deviation calculation unit configured to calculate an engine revolution speed deviation from a difference between an engine revolution speed and an engine revolution speed command;
• a revolution acceleration calculation unit configured to calculate an engine revolution acceleration on a basis of the engine revolution speed;
• a proportional torque calculation unit configured to calculate a proportional torque from a product of the engine revolution speed deviation and a proportional torque coefficient;
• and
• an integral torque calculation unit configured to calculate an integral torque via multiplying an integral of a product of the engine revolution speed deviation and an integral torque coefficient by a forgetting coefficient.

A method of controlling opening and closing of a throttle, comprising:

• receiving at least one data signal with an electronic control unit;
• calculating, via the electronic control unit:
• an engine revolution speed deviation from a difference between an engine revolution speed and an engine revolution speed command;
• an engine revolution acceleration on a basis of the engine revolution speed;
• a proportional torque from a product of the engine revolution speed deviation and a proportional torque coefficient;
• and
• an integral torque by multiplying an integral of a product of the engine revolution speed deviation and an integral torque coefficient by a forgetting coefficient;
• and
• providing, via the electronic control unit, a control signal for the throttle using a sum of the proportional torque and the integral torque as a torque command value.
