Electronic control method for throttle and electronic control throttle device

An electronic control throttle device, comprising:

• a throttle to which an actuator is attached;
• and
• an electronic control unit configured for opening and closing control of the throttle via the actuator and generating a control signal based on an input data signal;
• wherein the electronic control unit includes:
• a rotation speed deviation calculation unit configured to calculate an engine rotation speed deviation from a difference between an engine rotation speed and an engine rotation speed command;
• a rotational acceleration calculation unit configured to calculate an engine rotational acceleration based on the engine rotation speed;
• a proportional torque calculation unit configured to obtain a proportional torque from a product of the engine rotation speed deviation and a predetermined coefficient;
• and
• an integral torque calculation unit configured to obtain an integral torque by integrating a value obtained by subtracting a product of the engine rotational acceleration and the predetermined coefficient from the product of the engine rotation speed deviation and the predetermined coefficient;
• and
• wherein the electronic control unit is configured to generate the control signal for the throttle by using a sum of the proportional torque and the integral torque as a value of a torque command.
