智能桁架结构振动的仿人智能控制

为了研究高效实用的智能结构控制方法，将仿人智能控制（HSIC）应用于带压电作动器的空间桁架结构的振动主动控制，针对其稳定性差的缺点，提出包括模糊控制策略在内的三种改进方法。在Simulink中对三棱柱智能桁架结构的振动控制进行了仿真，并在MATLAB／dSPACE综合实验环境下进行了多种激励条件下的物理仿真实验。仿真和实验均使结构的一阶振幅迅速降低90％以上，对高阶频率的振动控制也取得满意的效果，表明HSIC能更快地控制结构振动，改进后的HSIC较好地解决了控制过程中快速性、精确性与稳定性之间的矛盾。

Human-Simulated Intelligent Control for Intelligent Truss Structures

Active vibration control of adaptive space truss structures with PZT stack actuator was studied by using Human-Simulated Intelligent Control(HSIC) methods.Three means have been adopted including fuzzy control method to improve the control stability.The control effectiveness is demonstrated through simulation with Simulink for an intelligent truss structure,and validated by experiments with various actuating forces in MATLAB/dSPACE environment.Numerical simulation and experiments show that the amplitude of the structural first mode can be reduced more than 90% rapidly with HSIC,and the control results of vibrations with higher frequencies are also satisfied.These indicate that using HSIC can control structural vibration more quickly,the improved HSIC can appropriately deal with the contradiction between rapidity,accuracy and stability of control.
