【摘要】 为了解决时滞问题带来的控制系统无线传输信号滞后问题，提高压电加筋板振动系统控制效果，提出一种基于改进幂次趋近律滑模算法的自适应Smith时滞补偿方法，并通过李亚普洛夫第二法则验证了稳定性，最终使得系统控制效果得到有效提升。实验结论表明，添加自适应Smith时滞补偿加筋板无线振动控制系统的控制效果为1.147V,相较于未添加自适应预估补偿的1.436V,改进后的振动幅值降低0.289V,控制效果提升13.50%。更多还原

【Abstract】 In order to solve the problem of wireless transmission signal delay of control system caused by time-delay and improve the control effect of piezoelectric stiffened plate vibration system, an adaptive Smith time-delay compensation method based on the improved power reaching law sliding mode algorithm is proposed, and the stability is verified by the second law of Lyapunov, and finally the control effect of the system is effectively improved. The experimental results show that: the addition of automatic control effect of the stiffened plate wireless vibration control system adapted to Smith time delay compensation is 1.147V. Compared with 1.436V without adaptive prediction compensation, the improved vibration amplitude is reduced by 0.289V, and the control effect is increased by 13.50%.更多还原
