摘要:
该文讨论了Skyhook控制策略的本质,建立了基于加速度和速度反馈的半主动减振系统控制策略,该控制策略能使被控物体在该文所选择的性能指标函数下得到近似最优控制。结果表明:该控制策略与Skyhook控制策略相比,能使被控物体的位移、速度、加速度及加速度变化率的平均绝对值分别降低38%7、0%8、6%8、6%,改善了物体响应的高频性能,能使物体响应的低频性能与Sky-hook控制策略相仿。
Abstract:
The substance of the Skyhook control is discussed and a new sem-i act ive vibrat ion control strategy based on acceleration feedback and velocity feedback is established. The proposed control strategy can make mechanical system close to optimal control under the proposed cost function. The results indicate: compared with the Skyhook control system, the proposed control strategy is more effective in the performance of vibration isolation and reduces the mean absolution values of the time response of the mass displacement , velocity, acceleration and acceleration change rate by 38 % , 70 %, 86 % and 86 % . The control strategy improves the amplitudes of the mass in the high frequency range and yields the same performance as the Skyhook control in the low frequency range.
