PURPOSE:To aim at ensuring rapid and precise responsiveness, by compensating the gain of feed-back in accordance with the opening degree of a throttle valve and the rotational speed of an engine in order that the feed-back control of the throttle valve is carried out by computing a desired intake-air pipe pressure in accordance with a desire torque. CONSTITUTION:A control circuit 60 carries out the map computation of a desired torque in accordance with a desired horse power and an actually measured rotational speed by an input shaft rotational speed sensor 78. Then, map computation is made to a desired intake-air pipe pressure in accordance with an actually measured engine rotational speed NE by an engine rotational speed sensor 76 and the desired torque. Further, the pressure differential DELTAP between the desired intake-air pipe pressure and an actually measured intake-air pipe pressure by a pressure sensor 72 is calculated, and a gain in a feed-back term is compensated in accordance with the engine rotational speed NE and a throttle valve opening degree measured by a throttle sensor 74 after initialization. Then, a throttle valve opening degree signal is delivered to an actuator 22. Thereby, it is possible to ensure rapid and precise responsiveness even though non- linearlity exists in the throttle opening degree or the intake-air pipe pressure. |
