【 摘 要 】

This study describes a two-stage control system using a dual-sampling method based on an optimal control scheme. The system consists of a speed-control system and a position-control system: the speed is controlled before the changeover point; after the changeover point, the position is controlled. For low speed and low sensor resolution, the proposed method uses position data estimated by an observer. The proposed method can control a plant with a low sensor resolution, unlike the conventional method, which has random oscillation in this situation. This method is confirmed through a simulation and by implementing a DC motor control.
