| Popis: | This paper proposed new position control method with acceleration feedforward compensation under the limited control bandwidth in the position control system of the EGR valve. This method estimates the acceleration reference through analysis of the relation between position controller output and speed reference without pattern and differential. The proportional gain of the position controller and the rotor speed are used to estimate the acceleration reference. Since the pattern generator is not used, the calculation amount is small and the influence of the noise caused by the differential is not affected. The usefulness of the proposed method is verified through simulation. |
