This paper presents a reference management considering the suppression of vibration for a two-dimensional (2D) transfer system. In this paper, the reference is generated by using sequential quadratic programming, which minimizes the cost function as the tracking error between target position and cart trajectory and energy of band for fluctuating resonance frequency. The proposed method enables the...
This paper presents modeling of a stepping motor with a full-step drive and design on the timing of the pulse inputs for the suppression control of vibration. When the stepping motor is shifted to the excitation phase, a torsional vibration occurs at the shaft part connecting to the motor due to an inertia load. Therefore, in the present study, a motor model considering a torsional vibration is designed...
This paper presents an advanced control system for a driving control system of an electrical wheelchair. The aim of the control system is to make possible a comfortable ride in the wheelchair. For this, a passenger model that uses a backrest in the wheelchair has been constructed and a driving pattern that suppresses a passenger's posture behavior has been developed using optimization methods. Then,...
