DSP에 기초한 모터 속도 제어용 2자유도 제어기 구현을 위한 시뮬레이션

In this research a simulation for implementing 2-D.O.F. motor speed controller based on DSP is carried out. By using the reference input and plant output, a 2-D.O.F. controller is expected to show better control performance than a simple feedback controller that is using only the difference information between the reference input and plant output. Additionally, it is well known that a 2-D.O.F. controller allows the control system to have better control performance without contaminating its stability. When a DSP is used for motor control, the 2-D.O.F. control scheme is easily to added to the original controller with adding some lines of program codes. The simulation of the motor speed control is carried out by taking account of input/output accuracy quantization characteristics of a DSP. The resultant program codes may be able to be used for an actual DSP controller.
