研究了热压电梁在热扰动作用下的动态变形控制问题。为了抑制由于扰动引起的变形，梁受到闭环控制过程，其中一个压电层作为传感器来检测由于扰动引起的变形，而另一个作为致动器来抑制它。根据经典层合板理论，给出了动力挠度的解析解。利用数值算例，研究了一系列电压脉冲对热扰动引起的暂态振荡的抑制作用。
Control of dynamic deformation of a piezothermoelastic beam with a closed-loop control system subjected to thermal disturbance is studied. To suppress the deformation due to the disturbance, the beam is subjected to the closed-loop control procedure where one of the piezoelectric layers serves as a sensor to detect the deformation due to the disturbance and the other as an actuator to suppress it. The analytical solution of the dynamic deflection is formulated based on the classical laminate theory. Using numerical examples, suppression of the transient oscillation due to thermal disturbance by a series of pulses of electric voltage is examined.
