摘要
Abstract
Mechanical model with 2DOF of 1/2 vehicle is established under road acceleration actuators and non - suspend molar is considered. The state equation and vibration differential equation of suspension system was deduced through selecting state variable. In the light of LQR optimal algorithm, the optimal control force is computed and approached by magnetorheological - damper semi -active control force computed from Delimitation -Hrovat optimal algorithm. The magnetorheological - damper semi - active control of suspension system was realized. The effects of active or semi - active vibration control with the sinusoidal road actuators were simulated, and compared with the effects based on passive control. The result shows that the mechanical model is reliable and the displacement and acceleration of the track vehicle are reduced greatly.关键词
