ABSTRACT:
A throttle valve controller includes a motor, a throttle valve driven by the motor, an accelerator sensor for setting a target position of the throttle valve, a throttle sensor for detecting the actual position of the throttle valve, a position control circuit for controlling the motor in accordance with a difference between the target position and the actual position of the throttle valve, a friction compensating circuit for compensating a positional error due to friction force affecting the throttle valve, and a driver for driving the motor with repetition of a control period in accordance with the position control circuit and the friction compensating circuit. The friction compensating circuit may compensate the positional error due to friction force during a control period together with the position control circuit. The motor may generate compensated torque in accordance with the friction force that affects the throttle valve. By doing this, the throttle valve may be controlled more accurately as if the resolution of the controller was increased.
