中文摘要
      在采用加速度传感器的振动主动控制平台中, 为了有效抑制外力可用微分方程描述的含输入时滞受迫振动响应, 基于积分变换和状态导数极点配置法, 提出了一种适应连续外扰的时滞加速度反馈控制器设计方法. 以粘贴有压电陶瓷和加速度传感器的受正弦激励的智能梁为仿真控制对象, 仿真结果表明, 此控制器能在任意输入时滞下有效抑制智能梁的持续受迫振动响应. 与不考虑时滞的同类控制器相比, 该控制器有较好的稳定性及控制效果.
英文摘要
      In the active vibration control system with acceleration sensors, a continuous disturbance-accommodating time-delayed controller using output acceleration feedback is proposed by means of integral transformation and pole displacement with state-derivative for the vibration systems. This controller can effectively suppress the forced vibration response suffering from a class of excitations satisfying a polynomial differential equation with input time-delay. The developed continuous time-delayed feedback controller is validated by the computer simulation which is particularly focused to the control of the forced vibration response of a cantilever beam with piezoelectric actuator and acceleration sensor. Simulation results demonstrate that the proposed controller can effectively reduce the forced vibration response of the intelligent cantilever beam under sinusoidal excitation with any time-delay. Compared with the continuous disturbanceaccommodating controller with acceleration feedback without time-delay, this controller has better stability and control effects.
