本文提出了一种控制策略，并进行了数值试验。这一战略的目的是在减少能源供应的情况下实现完全活跃的系统的潜在性能。这些能量需求预计将与半主动系统的功率需求相当，而系统性能将与完全主动配置的性能相当。其基本策略被称为“全局半主动控制”。这种控制方法是基于最优控制过程管理的能源调查的结果。能源管理包括存储和方便的恢复。提出的策略通过考虑纯耗散和耗能阶段，在没有任何外部能量供应的情况下监控给定的有源定律。文中给出了这种控制律，并对其性质进行了分析。文中还给出了一种适合于实际实现步骤的次最优形式。此外，为了验证试验结果，还进行了大量的数值试验。
In this paper, a control strategy is presented and numerically tested. This strategy aims to achieve the potential performance of fully active systems with a reduced energy supply. These energy needs are expected to be comparable to the power demands of semi-active systems, while system performance is intended to be comparable to that of a fully active configuration. The underlying strategy is called ‘global semi-active control’. This control approach results from an energy investigation based on management of the optimal control process. Energy management encompasses storage and convenient restitution. The proposed strategy monitors a given active law without any external energy supply by considering purely dissipative and energy-demanding phases. Such a control law is offered here along with an analysis of its properties. A suboptimal form, well adapted for practical implementation steps, is also given. Moreover, a number of numerical experiments are proposed in order to validate test findings.
