It is well known that inverted pendulums are difficult to control because of its non-minimum phase and non-linear characteristics. Car robot type inverted pendulums are developed and it provides small spacing than four wheel mobile robot. Moreover, car robot type inverted pendulums have high acceleration performance. In previous study, how to obtain the reference value of the body angle for driving at desired acceleration is proposed using zero dynamics of the non-linear system. This method use the exact values of the model parameters to obtain desired acceleration signal. Therefore, the robot cannot achieve desired acceleration if the plant parameters are different from its model parameters. So, it is necessary to minimize the effect of the model error to achieve robust acceleration performance. In this paper, we propose a method to achieve robust acceleration performance based on the model error compensator. Also, the performance of the model error compensator is improved using the virtual output to satisfy minimum phase condition. The effectiveness of the proposed system is evaluated by the driving experiments of a car robot type inverted pendulum.
