在本研究中，薄的智能梁的横向偏转的控制方程推导出相同的程序，伯努利-欧拉方程推导，但一些额外的数学术语是有效的描述智能梁。利用工程控制技术，得到了智能悬臂梁微分方程的解，并对该微分方程进行了一些辅助方程和修正，得到了以任意类型的载荷（静态或循环载荷）为输入，以梁挠度为输出的结构框图。为了保证有效地减少束流偏转，设计了一个由电压放大器和超前控制器组成的集成系统。许多情况下进行了研究和模拟，包括负载性质的变化，并在所有情况下，一个有价值的挠度减少的压电致动器/传感器对的数量。
In this research, the governing equation of the thin smart beam transverse deflection was derived by the same procedure that the Bernoulli-Euler equation derived but with some additional mathematical terms to be valid for describing the smart beam. The engineering control techniques were used to obtain the solution of the proposed differential equation for the smart cantilever beam where with some auxiliary equations and modifications a block diagram for any type of applied load (static, or cyclic) as the input and the beam deflection as the output was constructed. For insuring an efficient reduction in the beam deflection an integrated system with a voltage amplifier and lead controller was designed. Many cases were studied and simulated including the variation of load nature, and the number of collocated piezoelectric actuator/sensor pairs and in all cases a valuable deflection reductions were obtained.
