摘要：

In general, a single control algorithm is difficult to meet the conflicit requirements of a complicate suspension system. In this paper, a control system is designed to have a hierarchical structure and consists of an upper level controller and a lower level controller. The upper level controller generates the desired control output of the lower level controller and the lower level controller tracks the output of the upper layer. The upper level controller is designed to use H∞/generalized H2 output feedback control strategy for attenuating disturbances and improving energy regeneration efficiency. The generalized H2 norm is used to describe constraints and the H∞ norm is adopted to measure output performance. The lower level controller is designed to use state feedback integral strategy to track the output of the upper level controller. Numerical simulations are conducted to illustrate that the proposed method can attenuate disturbances and regenerate energy effectively. © 2020, Jilin University Press. All right reserved.
