    摘要:

    利用压电材料建立了单输入单输出理论模型并得到颤振方程及其状态空间方程。同时应用NASTRAN、MATLAB计算软件和自行编制的程序进行了气动力拟合,并且对模型的结构动力学特性及颤振特性进行了分析。计算结果表明,通过主动控制控制律的实施,达到了颤振主动抑制的目的。

    Abstract:

    Piezoelectric material was used to establish a single input/single output (SISO) model of a lifting surface with distributed piezoelectric actuators and piezoelectric sensors. The flutter equations and state space equations of piezoelectric laminated structures were also derived. MATLAB, NASTRAN and other software programs compiled by the authors also were used to analyze the flutter and dynamic characteristics. The stability of the closedloop was analyzed for the SISO. The result indicates that the control law can be employed for flutter suppression.
