摘　　要：提出了一种新的鲁棒自适应分段隐逆补偿状态反馈控制方案,以缓解智能材料驱动器中的双环回滞现象。其中,分段隐逆补偿方案不是真正意义上的回滞逆补偿器,而是一种在线解耦机制,从设计的临时控制信号寻找近似实际的控制信号。此外,提出了一种新的双环relay算子,从而建立了一种新的双环回滞模型。最后,在介电弹性体驱动器运动控制平台上进行实验,实验结果证明了所提出的输出-反馈控制方案的有效性。In this paper,a novel robust adaptive piecewise-indirect inverse output-feedback control scheme is proposed to mitigate double loop hysteresis in smart-material actuators.Piecewise-indirect inverse indicates that it is not a true hysteresis inverse compensator but an on-line decoupling mechanism to accessing the approximately actual control signal from the designed hysteretic temporary control signal.In addition,a new double loop relay operator is proposed for the first time,leading to the construction of a new model of double loop hysteresis.Finally,experiments are carried out on the dielectric elastomer actuator motion control platform,and the experimental results illustrate the effectiveness of the proposed output-feedback control scheme.
