- Abstract
- This paper proposes a design method for a high speed response motor system consisting of a motor and load. Various methods have been studied to improve the speed response of the motor system, but the main focus was previously advanced control techniques. However, the dynamic response of the controller can be further improved when the dynamic response of the plant improves. The proposed method improves the speed response by increasing the bandwidth of the motor system which is the plant of the servo system. Thus, the relationship between the bandwidth and speed response has been investigated. As the both electrical and mechanical parameters affect the speed response and bandwidth of the motor system, the correlation of the time constants and bandwidth were analyzed. Based on the analyzed results, the process of designing a motor system with maximized bandwidth was introduced. Therefore, a motor system with maximized bandwidth was designed using the proposed design process. Finally, the rated power and speed response of the motor system were verified through simulations.
