A semi-active suspension controller adapting to road variation
초록
In this paper, a semi-active suspension adapting to road variation which also considers the frequency snesitivity of human is proposed. First, a road adapting controller composed of system identification and LQG control is designed. Using the extended least squares method, the road property is estimated by system identification as it varies, and the LQG controller considering the estimated road property and the frequency sensitivity of human is designed. Next, the semi-active suspension is made, which tracks the performance of the active suspension with the road adapting controller. Through numerical simulation, the performance of the proposed semi-active suspension is compared with that of a non-adaptive semi-active suspension with frequency-shaped performance index. As a result, we see that the road adapting semi-active suspension has better performance.
