The invention relates to a general-purpose digital-analog hybrid gradient control system based on an FPGA. The system comprises a control configuration module, a control algorithm module, a control input module, a feedback input module, a control output module, a monitoring module, a communication module and a storage module. The control configuration module is used for coordinating and controlling the working of each module and monitoring the system status and alarm status of a controlled device in real time. The communication module is used for the communication with a host computer. The monitoring module is used for monitoring the system status in real time and emitting fault alarm. The storage module is used for storing system status information. The gradient control system of the invention can generate different control algorithms according to use requirements and is adapted to various load topologies. Voltage and current signals during an operation process are comprehensively monitored and recorded, the control is precise, and the system is safe to use. A high-speed communication interface is integrated, combined with the upper computer software, use parameters can be easilyset, and the status and waveform of each signal are visually displayed.
