2019년 11월 14일, 정정주 교수님께서 대만 지룽시에서 개최된 International Automatic Control Conference 2019 (CACS 2019)에서 초청 연설을 하셨습니다. 연설 주제는 비선형 모터 제어와 전력 계통 제어에 관련한 내용으로 약 1시간 동안 진행 되었습니다. 진행된 연설에 대한 요약은 다음과 같습니다.
"Nonlinear Control Method for Motion Control and Power systems"
In this speech, Prof. Chung introduced how nonlinear control methods developed by our research group have been applied to motion control and power systems. Steppermotors are widely used in industry due to its simple mechanism for control. He showed how various nonlinear control methods such as disturbance observer, various structure control, torque modulated micro stepping, nonlinear H2 control, and MISO back stepping, etc. are applied to the stepper motors for fast and precision motion control. He also showed how the torque modulation control can be extended to permanent magnet synchronous motor and how H2 control based on a linear parameter varying permanent magnet synchronous motor is implemented. Furthermore, he showed how nonlinear control methods including passivity based control, port-controlled Hamiltonian, dynamic extension, sliding mode control, grid voltage modulations, etc. are applied to power systems such as STATCOM, BTB STATCOM and PMSM wind turbine systems.
