摘　　要：提出了采用压电材料作为传感器和驱动器,基于模糊逻辑的柔性结构主动振动控制方法,并在嵌入式微处理器上实现模糊控制策略。柔性智能梁结构为例,以单片机为控制器,采用数值方法在计算机上模拟柔性结构模型,利用计算机与单片机的串行通讯技术实现了梁结构振动控制的硬件在环仿真,并编制出良好的人机界面和硬件接口程序。仿真结果表明本文提出的模糊控制方法能够很好的实现对智能梁结构的振动抑制。Based on fuzzy logic and embedded microprocessors, an active fuzzy control method is designed for flexible structures with piezoelectric materials as sensors and actuators. With a friendly user- computer interface, hardware - in - the - loop vibration control simulation for a cantilever beam is implemented by using the serial communication between a single - chip - computer serving as the controller and a personal computer including the structure numerical model. The results show that the method presented in the paper is valid.
