【Abstract】 An adaptive frequency-tracking and swing scan control algorithm has been presented.It was simple and effective in the industrial real-time controlling field, even the system frequency was changed. The results of simulation were satisfied. Using the control algorithm, a new digital controller has been designed with FPGA (Field Programmable Gate Array) in the swing scan control system.更多还原
