提出了一种新的半主动控制策略，该策略近似于参考主动控制的预测控制输出。在每个时刻选择半主动控制装置的可变参数，使得半主动控制系统的预测控制输出尽可能接近参考主动控制的相应预测控制输出。在上述“输出仿真”策略的前提下，对参考主动控制律的参数进行优化，使得半主动控制的控制性能变得良好，并且参考主动控制与半主动控制系统之间所达到的控制性能意义上的“误差”变小。采用基于线性矩阵不等式（LMI）框架的极点配置方法作为参考主动控制律。搜索参数以确定闭环极点所在的复平面中的域，从而优化基于输出仿真方法的半主动控制系统的控制性能。版权所有 © 2015 约翰·威利父子有限公司
A new semi‐active control strategy that approximates a predicted control output of a reference active control is proposed. A variable parameter of a semi‐active control device is selected at every time instant so that the predicted control output of the semi‐active control system becomes close to the corresponding predicted control output of the reference active control as much as possible. Parameters of the reference active control law are optimized in the premise of the aforementioned ‘output emulation’ strategy so that the control performance of the semi‐active control becomes good and the ‘error’ in the sense of achieved control performance between the reference active control and semi‐active control systems becomes small. A pole placement method based on a linear matrix inequality (LMI) framework is adopted as the reference active control law. Parameters to determine the domain in the complex plane where the closed‐loop poles are placed are searched so that control performance of the semi‐active control system based on the output emulation approach is optimized.
