Abstract：In the paper, a dimensionless version of the model oscillator is studied, the equation of motion is given as . Considering that the approximation expression of variable order(VO) differential operator is more complicated, it is difficult to design directly the controller, based on the curve analysis of displacement versus time, a truncation mode of VO differential operator is proposed, a concept of variable oblivion factor is proposed, meanwhile, an optimal controller is developed for the VO differential equation under study in order to reduce the dynamic responses.
