摘要
采用具有鲁棒性能的H2控制方法对海洋平台的过度振动进行控制,给出与控制效果相关的加权函数W1和与控制力相关的加权函数W2的表达形式,以一典型平台为例,重点分析加权函数中各参数对振动控制效果及所需控制力的影响趋势,并对加权函数中的各参数进行敏感性分析。
The H2 control method, which can be used to control the excessive vibration of the offshore platforms with robustness is adopted. The expressions of weighting functions W1 and W2 in H2 control method, which affect the control effect directly are presented. A numerical example is presented to illustrate the influence of weighting function parameters in H2 control on the control effect and required control force. The sensitivities of parameters in the weighting function are also studied.
