基于预测函数控制算法的柔性结构振动抑制研究

摘要

将系统离散化的状态空间方程作为预测模型,设计基于预测函数控制算法的柔性悬臂梁振动控制系统.预测函数控制算法减小系统的在线计算量,提高系统的实时响应能力.使用Matlab对振动控制系统进行仿真,结果表明该算法能够很好地抑制柔性悬臂梁的振动.%Taking the discrete state-space equation as prediction model, a flexible cantilever beam vibration control system is designed based on predictive-function control algorithm.The algorithm reduces the online computation and improves the real-time response ability of the system.The simulation results show that the algorithm is an effective method for vibration suppression.
