Abstract
- The aim of this study is to design a 4-degree-of-freedom linear-quadratic-Gaussian optimal controller for an active suspension to improve cargo integrity, under the condition of no loss of other properties. The analytic hierarchy process was used to reasonably determine the index weight, and simulation models of active and passive suspension systems were developed in the MATLAB and Simulink environment. By analyzing the time- and frequency-domain characteristics that are affected by suspension control, we observed that cargo integrity was effectively improved by the active suspension, and the road friendliness, ride comfort, and handling stability were also improved to some extent.
