The paper introduces the design principle and practical process of a hydraulic turbine regulator based on the chip DSP marked TMS320LF2812. Its fundamental functions are: to realize synchronous sampling to complete the accurate measurement for many kinds of simulation quantities using the synchronous sampling ADC module within the chip DSP; to bring about precision survey of frequency to utilize the high speed input function of the chip DSP; to obtain precision control signal output through PID and the optimum control method; and to accomplish the debugging on-line and the monitoring communication between multi-machine and super-position machine using the communication connection SCI in series and the CAN connection on the chip.
