Optimal Position of PZT Actuator and Control Experiment for a Flexible Plate
对柔性悬臂板主动控制中作动器的优化位置进行研究,其中作动器采用压电形式,优化算法采用粒子群方法,指标函数采用基于能量的可控Gramian优化配置准则。仿真和实验结果显示,粒子群优化算法能够有效地对作动器的优化位置进行计算,尤其适用于多个作动器的位置优化问题,基于作动器最优位置的控制设计能够取得良好的控制效果。
In this paper, optimal position of actuators on flexible cantilever plate is investigated, where PZT patches are used as actuators, particle swarm optimizer is used as optimization algorithm and energy-based controllable Gramian criteria is adopted as index function. Simulation and experimental results indicate that particle swarm optimizer is an effective algorithm for the calculation of optimal positions of actuators and is especially fit for the case of multiple actuators; the control design based on the optimal position of PZT actuator can obtain good control effectiveness.
