How about the quality of Karp electronic throttle in Taiwan Province Province?

Not so good. The Karp electronic throttle in Taiwan Province Province is not only affected by the nonlinearity of spring, stick-slip friction and clearance, but also by the nonlinear damping force generated by intake air flow and the resistance moment of the spoiler with unstable intake air flow, which leads to the failure of setting the feedback gain accurately by conventional PID control and affects the control accuracy.
