基于市场机制的TLCD半主动控制方案

基于市场机制控制是利用市场来模拟复杂的控制系统,用销售商和消费者来代替控制器和受控结构,从而将整个控制系统离散化,对结构的振动实施有效的控制。本文将基于市场机制的控制理论应用于TLCD半主动控制,提出了一种新的TLCD的半主动控制方案,即基于市场机制的TL CD半主动控制方案。首先建立TLCD-结构控制体系的运动方程,给出了半主动控制方案,用一个单自由度结构为例来阐述基于市场机制的TLCD半主动控制方案并对控制系统进行分析。然后用一个五层结构来验证这种方法的有效性。结果表明,基于市场机制的半主动TLCD开关控制不仅减振效果好,而且节约能量,简单易行,便于在实际工程中应用。

Control law for Market-Based Semi-Active Tuned Liquid Column Dampers

The complex control system can be simulated by market based control (MBC), where control devices and controlled structure are replaced by sellers and buyers, so the system is decentralized and the structure can be controlled effectively. A novel control law for semi active tuned liquid column dampers, market based control is presented. The equation of motion for structure TLCD control system is established and the MBC semi active TLCD control strategy is derived, and the semi active control strategy is illustrated with a one story structure. A five story structure is adopted to verify the effectiveness of the control method. The result indicates that MBC semi active TLCD on off control method facilitates reducing structure vibration with a lower energy expenditure.
