Adaptive high-rise buildings comprise sensors, a control unit and actuators and are able to actively compensate disturbances, allowing the realization of significantly lighter structures compared to conventional constructions. This publication presents the development of a force tracking controller for hydraulic actuators on adaptive high-rise buildings. First, nonlinear models of a single- and a double-acting hydraulic cylinder, used for two different ways of actuation in the structure, are derived. The characteristic curve for the valve cross-section is determined through experimental system identification. Second, a flatness-based input/output linearization is applied to both actuator models. A gain scheduling algorithm sets the proportional gain of the force tracking controller based on a measure reflecting the dynamics of the reference signal and thus avoiding control spillover due to mechanical coupling between the actuator and the structure. The force tracking controller is tested experimentally on the worldwide first adaptive building and its tracking behavior is analyzed based on the cutoff frequency of the closed loop system.

液压驱动自适应高层建筑的力跟踪控制

自适应高层建筑由传感器、控制单元和执行器组成，能够主动补偿干扰，从而实现比传统建筑更轻的结构。该出版物介绍了自适应高层建筑液压执行器的力跟踪控制器的开发。首先，推导了用于结构中两种不同驱动方式的单作用和双作用液压缸的非线性模型。阀门截面的特性曲线是通过实验系统辨识确定的。其次，基于平坦度的输入/输出线性化应用于两个执行器模型。增益调度算法根据反映参考信号动态的测量来设置力跟踪控制器的比例增益，从而避免由于致动器和结构之间的机械耦合而导致的控制溢出。力跟踪控制器在全球第一座自适应建筑上进行了实验测试，并根据闭环系统的截止频率分析了其跟踪行为。
