Study on Design PI Controller Adopted Sliding Mode Control for DC Servo Motor Position Control

슬라이딩 모드 제어 이론을 적용한 PI 제어기에 의한 직류 서보 모타의 위치 제어에 관한 연구

This paper proposes new position control method for DC servo motor by PI controller adopting sliding mode control. By adding sliding mode controller to conventional PI controller good robustness is obtained with good transient response and no steady state error which are merits in PI controller. In order to use microprocessor for digital control the principles of sliding mode control conventionally explained in continous-time system are extended to discrete-time system.
