A strategy for compensation and control of thermal softening effect for a new kind of viscoelastic dampers isproposed. By inputting proper control current to the damper according to the real-time temperature, the softening effect ofthe damper at high temperature can be compensated. Therefore, intelligent control devices are the core of the dampercompensation control. In this paper, a thermal compensation intelligent control device based on pulse width modulationtechnique is developed. The results show that this intelligent control device is of high accuracy and the thermal softeningeffect can be compensated well by this control strategy. The control accuracy and the compensation effect can meet theactual engineering needs of the dampers.
